TThe Applied Element Method (AEM) is a relatively recent addition to the discrete elements methods family. Initially conceived to model blast events and concrete structures, its use in the modelling of masonry structures subjected to earthquake actions is steadily...
Blast Analysis
Extreme Loading for Structures – Version 6.0 Released!
We’re happy to announce the release of our Advanced Structural Analysis Software, Extreme Loading for Structures (ELS) Version 6.0! ELS is used by structural engineers and researchers around the world to study the effects of blast, progressive collapse,...
Using the applied element method for modelling calcium silicate brick masonry subjected to in‐plane cyclic loading
The response of calcium silicate unreinforced masonry construction to horizontal cyclic loading has recently become the focus of experimental and numerical research, given its extensive use in some areas of the world that are now exposed to induced earthquakes (eg,...
Blast Analysis and Design of Reinforced Concrete Slabs with FRP Retrofit using ELS
Ahmed Khalil, P.E, Ph.D from ASI and Tarek Kewaisy, P.E., Ph.D. from Louis Berger will be co-presenting a paper titled “Advanced Modeling of Blast Response of Reinforced Concrete Slabs with and without FRP Retrofit” on March 26 2018 at ACI Concrete...
Establishing a Predictive Method for Blast Induced Masonry Debris Distribution Using Experimental and Numerical Methods
When subjected to blast loading, fragments ejected by concrete or masonry structures present a number of potential hazards. Airborne fragments pose a high risk of injury and secondary damage, with the resulting debris field causing major obstructions. The capability...
New Methodology of Designing for ATFP Using Modified Alternate Load Path Method
A new methodology to design against disproportionate collapse is proposed for critical building that must be operational after a terrorist attack. The disproportionate collapse analysis uses the alternate path method where the structure must be designed to support the...
Visit ASI at Structures Congress 2017!!
Come visit us at this year's Structures Congress in Denver, Colorado. We have staff presenting on topics using our Extreme Loading® for Structures (ELS) in the following sessions: Ship Impact & Nonlinear Dynamic Collapse Analysis of a Single Well Observation...
The Influence of Structural Arrangement on Long-duration Blast Response of Annealed Glazing
This paper investigates the influence of structural arrangement on long-duration blast loaded annealed glazing via variable thickness, area, aspect ratio and edge support conditions. Initially, the findings of eighteen full-scale air-blast trials employing 33 annealed...
Numerical Investigation of Reinforced Concrete Barriers Subjected to Blast Loading
People’s lives are threatened by explosions; the tragic terrorist attacks have forced the governments to consider the importance of dealing with these attacks. With the rising threat of terrorism, protecting critical civil infrastructure such as embassies,...
