ABSTRACT Explosions bring a serious risk of damage or collapse when are produced inside buildings or in the close proximity. As the hazard intensity and possible effects are difficult to quantify, the structure should have the capacity to survive with inherent...
Abstract: The evaluation of the seismic vulnerability of historical masonry buildings is a difficult task due to the uncertainty regarding structural characteristics and construction techniques, mechanical properties, and pre-existing damage. Hence, there is a need...
ASI’s paper on the progressive collapse of the Polcevera Viaduct Bridge in Genoa, Italy will be available free for the next 50 days from Engineering Structures. ASI Engineers modeled up the bridge and simulated the collapse using its Extreme Loading for...
Glazing systems are widely used in office buildings around the world. They provide an open space feeling for the building occupants, and this makes them an attractive option. Unfortunately, they have a weakness, they are vulnerable to blast pressure induced from...
ASI will be attending the 2019 Structure Congress in Orlando, FL from April 24-27, 2019. ASI sessions this year focus on the Protective Design for Structures and industrial facilities. Below are the Sessions that ASI is participating in. ASI Engineers will also be...
Ahmed Khalil, Ph.D., P.E. will be presenting a paper entitled, ” Nonlinear Dynamic Alternative Load Path Analysis of 10-story Concrete Shear Wall Flat Plate Building”, at Structures Congress 2019, Saturday, April 27th from 8:00 – 9:30 AM in the...
It's time to take dust control seriously by leaving dated technology and inefficient dust control analysis methods behind. Dust control upon building implosion is essential in maintaining healthy air quality, following government regulations, and supporting the best...
On 14 August 2018 at 11:35 AM, a relevant portion (about 243 m) of the viaduct over the Polcevera river in Genoa collapsed, killing 43 people. The bridge was designed in the early 1960s by Riccardo Morandi, a well-known Italian engineer, and opened to the public in...
In this article, we take a look at blast analysis with a focus on SBEDS (Single Degree of Freedom Blast Effect Design Spreadsheet) vs ELS (Extreme Loading for Structures). Our goal is to explain why ELS should be considered over SBEDS for blast analysis. Firstly,...
