Performance-Based Seismic Vulnerability Evaluation of Masonry Buildings Using Applied Element Method in a Nonlinear Dynamic-Based Analytical Procedure(7/8/2013 )
 

Durham, N.C. July 8, 2013 - Earthquake Spectra Journal Publication:  Performance-Based Seismic Vulnerability Evaluation of Masonry Buildings Using Applied Element Method in a Nonlinear Dynamic-Based Analytical Procedure

This paper studies the performance based vulnerability assessment of midrise masonry structures against seismic activity using Extreme Loading® for Structures (ELS) 

Abstract: A thorough four-step performance-based seismic evaluation for a six-story unreinforced masonry building is conducted. Incremental dynamic analysis is carried out using the applied element method to take advantage of its ability to simulate progressive collapse of the masonry structure including out-of-plane failure of the walls. The distribution of the structural responses and inters-tory drifts from the incremental dynamic analysis curves are used to develop both spectral-based (Sa) and displacement-based (interstory drift) fragility curves at three structural performance levels. The curves resulting from three-dimensional (3-D) analyses using unidirectional ground motions are combined using the weakest link theory to propose combined fragility curves. Finally, the mean annual frequencies of exceeding the three performance levels are calculated using the spectral acceleration values at four probability levels 2%, 5%, 10%, and 40% in 50 years. The method is shown to be useful for seismic vulnerability evaluations in regions where little observed damage data exists.

World Demolition Awards 2011 - Fabio Bruno Construçoes wins the Explosive Demolition Award (11/4/2011 )
 

Amsterdam,Netherlands, November 4, 2011 – Durham, NC – World Demolition Awards 2011, Fábio Bruno Construções wins the Explosive Demolition Awards

Fábio Bruno Accepts 2011 Explosive Demolition AwardCongratulations to Fábio Pinto Bruno and his team at Fábio Bruno Construções, who has just taken home the Explosive Demolition Award from the 2011 World Demolition Summit held in Amsterdam this past weekend.  The Explosive Demolition Award is one of twelve categories presented at the Gala dinner during the Demolition Summit.  Fábio Bruno Construções won the award for two of its latest implosions University Hospital in Rio de Janeiro, Brazil and Castelão Football Stadium in Fortaleza, Brazil.

Applied Science International (ASI) is proud to have worked with Fábio Bruno Construções in the design and analysis of demolition plans for both projects using its proprietary Extreme Loading® for Structures software (ELS).  In both projects ASI modeled the “as built” and “as damaged” condition of the structures in 3D including masonry walls, columns, beams, slabs, reinforcement details, pre/post tensioned cables, elevator shafts, expansion joints, and temporary shoring in its ELS software for analysis of the demolition plan. The models also included material decomposition of both the concrete and steel reinforcement in corroded areas of the structure so they best reflected real-world conditions.   

Once the model was created, the team was able to analyze several demolition scenarios, studying the entire demolition sequence from initial failure, through to separation and collapse.  This allowed the team to optimize the placement of explosives, weakening and estimation of debris fields. Throughout the process ASI and Fábio were able to see the results of each proposed scenario to determine the proper sequence and locations of charges for a safe demolition. 

The University Hospital implosion involved the demolition of the deteriorating half of a 16 story, 25,000m2 structure.  The owner was only using half of the building while the remaining half fell to deterioration over the years.  The requirements for the demolition plan were particularly challenging because the owner wanted to safely remove the deteriorated section of the structure while leaving the remaining wings operational.  Fábio Bruno Construções proposed a demolition plan that included the manual demolition of a 15m section of the building.  This roughly divided the structure in half to allow the implosion of the deteriorated half of the structure away from the occupied portion.

The Castelão Football Stadium project involved the removal of several sections of the cantilevered stadium by controlled collapse, with the remaining structure to be renovated in preparation for the upcoming 2014 World Cup.  This was a implosion was a challenge because of the sensitivity of both the remaining sections of the stadium and the 3-story structure located less than 13m behind the cantilevered stadium.  With ASI, Fábio Bruno Construções worked to create a demolition plan that would both efficiently collapse the stadium sections while keeping the remaining stadium sections and surrounding structures undamaged.  An initial concept was developed to utilize the cantilevered action of the upper seating area as a pivot point allowing the area to rotate down around it, increasing the gap between the 3 story building and the stadium.   A variety of demolition scenarios were analyzed in ELS to determine the size of the compression zone that needed to be blasted for it to create a plastic hinge allowing for this rotation.

For both projects, due to the location of adjacent buildings and sensitive equipment, ASI simulated the effects of debris in causing temporary ground acceleration in the soil. This was important as high velocity impact from building debris on varying soil composition can be hazardous to surrounding infrastructure both above and below ground. Through this analysis all ground acceleration levels from impacting debris were determined to be within acceptable limits.

 
Aspects Concerning Progressive Collapse of a Reinforced Concrete Frame Structure with Infill Walls(11/3/2011 )
 

Durham, N.C. November 3, 2011 - The World Congress on Engineering Proceedings Paper:  Aspects Concerning Progressive Collapse of a Reinforced Concrete Frame Structure with Infill Walls

This paper regarding the use of Extreme Loading® for Structures (ELS) to study progressive collapse was recently published in the proceedings of the World Congress on Engineering held this summer in London, UK.  The authors study the effects of infill walls in progressive collapse cases in which they found exterior infill walls to support extra gravity loads after vertical element removal.  The study highlights the importance of studying structural and non-structural components typically ignored in progressive collapse design.

Abstract: The present paper proposes modern approaches, nonlinear static and dynamic analysis procedures based on the Applied Element Method, to assess a progressive collapse problem of a RC frame structure with infill walls. Comparisons between the results of modeling alternatives for a 6-story building: bare frames, exterior frames with infill full walls, openings or with windows (casement and glass) for two different columns removal approaches (demolition and blast scenarios) were made.

Keywords: Progressive collapse, Applied Element Method, demolition, blast, infill walls.

Computer-Aided Design of Framed Reinforced Concrete Structures Subjected to Flood Scouring (10/28/2011 )
 

Durham, N.C. October 3, 2011 - The Journal of American Science Article Published: Computer-Aided Design of Framed Reinforced Concrete Structures Subjected to Flood
Scouring

The Journal of American Science, has recently accepted and published a paper entitled, "Computer-Aided Design of Framed Reinforced Concrete Structures Subjected to Flood Scouring."

In the paper, author Hamed Salem, Ph.D., studies the performance reinforced concrete structures with tie bean reinforcement against progressive collapse caused by the scouring of soil beneath the foundations. Based on his research using the fully non-linear dynamic capabilities of AEM, the author was able to study the failure of the structure through complete collapse, determine the mode of failure, and then propose mitigating designs to prevent such a collapse in the future. The entire paper can be accessed using the link below.

Abstract: In the beginning of 2010, several reinforced concrete structures collapsed due to floods in Sinai and Aswan, Egypt. Scour of soil beneath foundations lead to excessive differential settlements, failure of main structural members and finally complete structural collapse. A three-dimensional nonlinear dynamic analysis of a multi-storey reinforced concrete framed structure with induced soil scour under its foundation is carried out using the Applied Element Method. The analysis of the structure is followed until its complete collapse. The numerical analysis is then used to propose a safe design against collapse. Three different alternatives proposed for preventing progressive collapse are independently investigated; floor beams, tie beams connecting footings, and diagonal bracings.

Increasing the size of the floor beams was found not to have significant effect on mitigating progressive collapse, while the use of diagonal bracings in the ground floor or rigid tie beams connecting the structure’ footings was found to efficiently prevent progressive collapse. With diagonal bracings or rigid tie beams, the excessive differential settlements of the footings can be eliminated and the gravity loads can follow a safe alternative path preventing the structural collapse. The tie beam reinforcement was found to have a significant effect on the structural behavior during such an extreme loading case. Section analysis of the tie beam suggests that its ultimate strength should be based on rupture of main reinforcement, which is more economical and appropriate for such loading case.

Keywords: Flood scouring, progressive collapse, Applied Element Method, tie beams.

Journal of Performance of Constructed Facilities Article Published: Enhanced Modeling of Steel Structures for Progressive Collapse Analysis Using Applied Element Method(8/3/2011 )
 

Durham, N.C. August 3, 2011 - ASCE, Journal of Performance of Constructed Facilities Article Published: Enhanced Modeling of Steel Structures for Progressive Collapse Analysis Using Applied Element Method

The Journal of Performance Constructed Facilities, an ASCE publication has recently accepted and published a paper entitled, "Enhanced Modeling of Steel Structures for Progressive Collapse Analysis Using Applied Element Method." 

In the paper, author Ahmed Amir Khalil, Ph.D., discusses performing progressive collapse analysis of steel structures based on UFC 4-23-03, 2010 and GSA 2003 codes. Based on his research, the author concluded that the use of nonlinear dynamic analysis allows the engineer to more accurately model by including the slab and reinforcement while also reducing the number of load cases required. The entire paper can be accessed using the link below.

Abstract: This paper studies performing progressive collapse analysis for steel structures using the requirements of recent codes released by the United States Department of Defense and the General Services Administration. Based on review of the code requirements, nonlinear dynamic progressive collapse analysis results in a more uniform factor of safety than linear static analysis. The Applied Element Method in structural analysis is proposed as an efficient alternative for performing progressive collapse analysis. A case study is undertaken where the results of progressive collapse analysis using traditional Finite Element Method simplifications are compared to the results from the Applied Element Method in the analysis of a moment resisting steel frame. The case study shows that simplifications that are usually done in finite element analysis when studying traditional load cases can be over-conservative when performing progressive collapse analysis. The results show that the use of the nonlinear dynamic Applied Element Method while taking into account the effect of secondary members such as slabs and secondary beams can lead to considerable savings in the total weight of the steel frame.

Engineering Structures Journal Article Published: Toward an Economic Design of Reinforced Concrete Structures Against Progressive Collapse (8/2/2011 )
 

Durham, N.C. August 2, 2011 - Engineering Structures Journal Article Published: Toward an Economic Design of Reinforced Concrete Structures Against Progressive Collapse 

Engineering Structures, a world renowned journal for scientific and technical papers on the topics of structural engineering and structural mechanics has recently accepted and published a paper entitled, "Toward an Economic Design of Reinforced Structures Against Progressive Collapse." 

In the paper, authors Salem, El-Fouly, and Tagel-Din discuss the use of the Applied Element Method (AEM) in the design of reinforced concrete structures against progressive collapse.  Based on their research, the authors conclude that the use of AEM can bring about a 50% reduction in the amount of reinforcement in the structure compared to Linear FEM. This is because the user can easily model reinforcement details, taking into account material nonlinearity, large deformations, failure, separation and collision. 

ASI is the only commercial company to implement the AEM in its software Extreme Loading® for Structures. The entire paper can be accessed using the link below.

Abstract: A three-dimensional discrete crack model based on the Applied Element Method is used to perform economic design for reinforced concrete structures against progressive collapse. The model adopts fully nonlinear path-dependent constitutive models for concrete and reinforcing bars. The model applies a dynamic solver in which post-failure behavior, element separation, falling and collision are predicted.  First, the model is used to study the behavior of multi-story reinforced concrete buildings designed in a traditional manner according to the ACI 318-08 and subjected to accidental removal of one or two central columns at the ground level. In an iterative way, the model is then used to investigate a safe design against progressive collapse for such extreme loading case. Based on the analytical results of the AEM, it can be concluded that the collapse of only one column would not lead to any progressive collapse of the studied reinforced concrete structure. However, the collapse of more than one column may lead to a progressive collapse of a considerable part of it. It is concluded also that the AEM could be successfully used as an analytical tool to suggest economical designs that are safe against progressive collapse of reinforced concrete structures.

Read the performance based design white paper, UFC Progressive Collapse: Material Cost Savings, that shows how you can save 20-30% in the weight of the structural system using ELS.

 

In the study ASI compares simplistic procedues which model only linear beam and column elements to more advanced procedures which model the nonlinear effects of all structural components (columns, beams, slabs, and reinforcement).  ASI found that analysis using simplified finite element linear and nonlinear analysis suggested a significant increase in the weight of the steel frame is required to satisfy the UFC progressive collapse code requirements. Using more advanced analysis, like Extreme Loading® for Structures (ELS) software shows that the original design required little to no increase in weight required.

 
Implosion of the Rio de Janeiro University Hospital (12/19/2010 )
 

Durham, N.C. December 19, 2010 - Implosion of the Rio de Janeiro University Hospital. Fábio Bruno Construções Ltda successfully imploded the South wing of the Rio de Janeiro University Hospital with the help of ASI's advanced demolition analysis services.

The hospital, considered to be the first reinforced concrete structure in Rio consisted of 16 floors with an area of 11,266m2 and a total of 55,000m3 of concrete.  This was a particularly interesting project because the project owner wanted to retain the North wing of the structure and continue operating it as a hospital.

The demolition plan called for a 20m section of the structure to be demolished manually and the remaining South wing to be imploded.  ASI modeled the South wing with all of its structural details in 3D including columns, beams, girders, slabs, masonry walls, expansion joints and reinforcement.  The model also included weakened material models in corroded areas of the structure, making it as accurate to real-world conditions as possible.

Through ASI's analysis the demolition plan was optimized to ensure that the structure collapsed completely and did not collide with the North wing.  ASI also performed a seismic analysis of the impacting debris on the soil to ensure sensitive medical equipment in the North wind and surrounding medical buildings was not adversely affected. 

After the successful implosion, Fabio Bruno, Director Operacional of Fábio Bruno Construções Ltd said, "The implosion went exactly the way as planned and the client was very pleased with the accuracy. We feel that simulation is one tool that helps predict mistakes that otherwise could happen, and although some are against use of the technology, we feel that the more information we have the less chance that mistakes can happen."

Fabio Bruno Construçoes - Quality Leap in Implosion (12/15/2009 )

Fábio Bruno Construções took a quantum leap over other companies using a simulated implosion before the fall of the buildings known as Skeleton Man, in Santa Cruz. 

For the first time in Brazil a simulation of the implosion was used in partnership with the American company ASI (Applied Science International, LLC). With a simulation, Fabio Bruno could predict the possible risks, ensuring the technical quality of the buildings in the fall, limiting the problems of vibration, release of debris and ensuring the safety of surrounding areas. 

The theory was confirmed by the survey conducted after the implosion in all buildings within a radius of 50 meters, proving that the simulation met all expectations. For the implosion held on day 01 of December 2009, engineers and technicians Fabio Bruno started working on site preparation, on 17 November with the drilling of the blocks, protection against ultra-release and installation of 100 pounds of dynamite to bring down the buildings.

The buildings, both with 9 floors, located at Rua Alvaro Alberto, had structural damage that put the buildings at risk and were condemned for more than a year by Civil Defense.

Blast Analysis (5/7/2009 )
 

Because the behavior of a structure during a bomb attack or accidental blast is critical to the integrity of the structure and the safety of its inhabitants, understanding the failure mechanisms is what will aid in reducing casualties and protecting investments.

ASI applies a one-of-a-kind structural analysis technology to analyze and simulate the nonlinear behavior of structures during blast events. This analyzing and visualizing of the reaction of structural and nonstructural elements helps both in the design of better performing structures and in the determination of the upgrades necessary for mitigating losses.

ASI’s Applied Element Method (AEM) based Extreme Loading® Technology is the only analysis method for accurately examining the behavior of a structure during blast and the structure’s resultant failure points. By being able to analyze and predict the nonlinear and failure modes of structures, ASI’s engineers can:

  • Test the global performance of a structure and its envelope
  • Identify weaknesses and potential upgrades
  • Determine failure and casualty mechanisms

ASI’s blast analysis is based on solid engineering models that include the following:

  • Blast modeling derived from military design codes
  • Precise structural modeling that includes structural and non-structural components

Blast analysis services include:

  • Blast performance analysis
  • Advanced Applied Element analysis
  • Debris modeling
  • Structural upgrades and retrofits for blast resistance
  • Window upgrades for the reduction of blast effects

ASI Obtains Safety Act Designation for Anti-Terrorism (7/24/2008 )
 

On July 24, 2008 Applied Science International’s Extreme Loading® for Structures software was assigned Designation Status for Anti-Terrorism under the SAFETY Act by the Department of Homeland Security.

The Support Anti-terrorism by Fostering Effective Technologies Act of 2002 (SAFETY Act) – “provides important legal liability protections for providers of Qualified Anti-Terrorism Technologies – whether they are products or services. The goal of the SAFETY Act is to encourage the development and deployment of new and innovative anti-terrorism products and services by providing liability protections. For more details, see the SAFETY Act Final Rule.

Extreme Loading® technology is based on ASI’s implementation of the Applied Element Method (AEM), a breakthrough development which simulates automatic crack initiation, separation of materials, and collision of materials closer to reality than any other structural analysis technology.  Extreme Loading® for Structures (ELS) is a one of a kind tool currently used for physical security assessments, advanced structural engineering applications including blast analysis, progressive collapse analysis, seismic analysis, forensic analysis, performance based design, and demolition planning and prediction.

ELS can be used to analyze a wide variety of structures including bridges, towers, and sports arenas; a broad range of building materials; and different phases of structural design.  ELS visuals allow first responders to become integral participants in the development of threat scenarios for crisis management planning.  The software aids in the design, analysis, protection, retrofit and demolition of structures, and it is the only structural analysis tool that provides the capability to simulate everything from a local failure to the global response of the structure.  A Special Report addressing ASI’s technology issued by the Homeland Defense Journal and titled “Changing the Known Built World” is available for downloading at:

ASI’s Extreme Loading® Technology Allays Implosion Concerns (3/22/2008 )
 

Extreme Loading® Technology was used to predict the collapse of St. Francis Hospital scheduled for demolition in Pittsburg, Pennsylvania last weekend. The building’s demise was historic to that locale, but for Applied Science International (ASI), the hallmark event is about the technology that showed the public what would happen beforehand – a new structural analysis technology now available to practicing engineers internationally.

Following close on the heels of its previous successes, Applied Science International’s proprietary Extreme Loading® technology has once again been used to allay contractor and civic concerns by precisely predicting the outcome of a major implosion. Just as it did previously with the demolition of the historic Charlotte Coliseum on June 3 of last year and the Stubbs Tower in Savannah, Georgia a few months ago, ASI accurately ran an engineered simulation of the event for the parties involved.

With St. Francis Hospital now in an uncertain, partially demolished state, ASI was called upon by the Pittsburgh-Allegheny County Sports and Exhibition Authority (SEA) to determine whether the structure was in eminent danger of collapse or safe enough to be entered so that explosive charges could be planted. ASI worked closely with SEA, Homrich Demolition (the prime contractor), and Dykon Explosive Demolition (the implosion subcontractor) to implement the planned demolition via an engineered simulation that coupled their demolition expertise with ASI’s analytical technology.

SEA released the engineered simulation to local media and news agencies for public viewing prior to the scheduled implosion, and with SEA’s concerns addressed, the go-ahead was given. Within a few thundering moments, St. Francis was reduced in a series of controlled explosions to a neatly stacked pile of rubble.

“The major factor here is not that the building came down as predicted; we were certain of that,” said ASI’s CEO Edward diGirolamo. “Rather, it was a chance for us to employ our 64-bit capability and all of the advantages it possesses. It was one of the largest and most comprehensive structural models we have run to date and we are very pleased with the results.”

While a demolition is a scheduled event, the same cannot be said of a terrorist attack, a hurricane, or an earthquake,” continued diGirolamo. “This predictive technology is based on the Applied Element Method, which was first developed at Tokyo University after the Kobe Earthquake claimed thousands of lives. The technology is now available as a diagnostic tool to answer the “What if” question before an event takes place, thereby allowing for the taking of preventative measures to mitigate the effects of a catastrophe, or as a forensic tool to answer the “What happened” question; regardless if that catastrophe was natural or man-made.”

Currently, ASI’s technology is used for homeland defense, physical security assessment, forensics, demolition planning, and structural analysis. It is now available for engineers to use in the engineering analysis of seismic, wind, collapse, progressive collapse and other extreme loading events. ASI’s technology is now available to practicing engineers and its analysis output provides visualizations of the structure’s behavior in a format that is easily understood by engineer and non-engineer alike (www.appliedscienceint.com).

ASI’s sister company TSNStudios is also involved, as the unprecedented realism generated by this software is making it an ideal fit for film production, entertainment and gaming industries. Combining the power of an engineered simulation and its export into the industry’s film and visual effects tools, makes this technology a real contender for the next blockbuster production where material separation, demolition and destruction effects are important (www.tsnstudios.com).

“We believe that ASI’s Extreme Loading® technology will eventually affect more than forty different fields of science where material separation is important to the outcome. Our experience with the demolition community has certainly contributed to the advancement of the science to understand the behavior of structures and collapse, and it is, in our opinion, the most ideally suited technology for the task.”  concluded diGirolamo.

Applied Science International Demonstrates New Technology (6/28/2007 )
 

Raleigh, North Carolina June 2007 --- Applied Science International, LLC, a subsidiary of The Steel Network, Inc., opened a new era in engineering simulation with a dramatic demonstration of its breakthrough technology, the ability to accurately predict the progressive collapse of a structure prior to an actual implosion or other extreme loading threat (blast, earthquake, hurricane winds, etc.).

On June 3rd, the historic Charlotte Coliseum was demolished in a spectacular 13-second implosion, leaving only a pile of metal, concrete, and rubble to mark the spot where this celebrated structure once stood. What singled this event out from all other implosions, however, was the historic significance attached to its deconstruction. Because of the utilization of ASI’s revolutionary technology a demolition plan was fully simulated and the results were demonstrated to the developer and the general and demolition contractors before the implosion.

When asked about the drive behind the creation of this new technology, ASI Chief Executive Officer, Edward di Girolamo stated, “Our goal began almost 12 years ago with the desire to create a new technology that would be capable of completely redefining how buildings are designed, analyzed, constructed, protected and demolished.”

“By reinventing the approach currently used (one that was developed in the 1940’s), we have created the capability to predict and visualize a structure’s behavior in a manner found nowhere else.”

“This demonstration is the first time an actual full motion, virtual reality, engineering simulation has been created for a demolition beforehand. What most spectators saw and heard was a series of explosions, a dust cloud raised from the collapsing structure, and disappearance of the roof line behind the cloud. What ASI was able to demonstrate was the progressive collapse of the coliseum from start to finish and from every desired angle - both inside and outside of the building.

”The ramifications of this are staggering,” continued di Girolamo. “By utilizing this technology, we can analyze any structure, no matter how large or how small, predict how it will react to an external force, and then protect that structure from unnecessary damage.”

Today ASI applies its technology in construction design and analysis, in vulnerability assessment and risk mitigation planning, in forensics, and in deconstruction. ASI’s technology and this historic simulation were unveiled at the Homeland Defense Conference sponsored by the Homeland Defense Journal on June 27, 2007 to be followed by a Special Report in July 2007. The event in Charlotte not only demonstrates ASI’s plans to change the way engineers build, protect and demolish structures, it signals the onset of a new era in simulating the known built world.

ASI at the 34th National Demolition Associations Annual Convention (4/5/2007 )

 

ASI successfully participated in the National Demolition Association’s annual conference this year in Las Vegas. We were well received by the demolition community and to some, considered one of the highlights of the show. Demolition general contractors, government officials, building owners, demolition consultants, insurance agents and several of the world’s leading experts visited our booth and discussed our services.

Many were excited about using demolition simulations for their bids and proposals and to advertise their portfolio, improve safety, get approval of their plans in their region, and for educating future demolition experts.

We at ASI appreciate the warm welcome we received from the NDA and its participants. It was a very family oriented show and we felt like we were a part of it.

 
Applied Science International featured in the Homeland Defense Journal (3/15/2007 )

 

As appears in Vol. 5 Issue 3 of Homeland Defense Journal.

Applied Science International, LLC, Raleigh, N.C., has developed a new technology that models and simulates the behavior of structures subjected to explosions, earthquakes, hurricane force winds and progressive collapses. Collectively classified as extreme loading conditions, the amount and duration of the forces applied are what need to be understood in order to prevent disastrous consequences. Accurate Vulnerability and Risk Assessment is what ASI’s breakthrough technology provides in the face of both man-made and natural threats.

ASI developed the ability to create a near virtual reality scenario, allowing its clients to see a full motion video of what will happen when an event takes place, whether it’s a bomb within a building’s perimeter, an earthquake underneath it, or a hurricane assaulting it from the side. ASI’s Risk Assessment Service takes the guess work out of decision making by partnering with building owners, security providers, property management firms, structural engineers, insurance underwriters and demolition contractors to leverage expertise during the assessment process. ASI’s team of scientists and engineers has improved the risk assessment processes and progressive collapse guidance now available in FEMA, DoD and USACE publications.

ASI developed the Applied Element Method (AEM) to more closely approximate reality than the standard Finite Element Method (FEM). AEM simulations allow elements to separate during failure and collide with adjacent elements; the way it really happens. FEM simulations appear as melting plastic models with no separation of elements.

ASI can easily model a glass panel or multi-layered panels and connections and simulate behavior under extreme loads, contributing significantly to material selection, casualty assessment and wind-blown hazard analysis. ASI’s AEM-based tools model and simulate threat scenarios - in hours not days. This rapid-prototyping capability allows engineers and security firms to consider
performance-based design options more quickly and thoroughly - in days not weeks.

Visualizing predicted structural response brings a new level of understanding and informed decision making to constructing, retrofitting or securing a building through a modification of the structural design, a relocation of key assets, an extension of the building’s perimeter, a changing the of the glazing, or the implementation of new security procedures.
