Numerical prediction of progressive collapse of buildings due to extreme loading is still a challenging task. However, increased computational power makes it nowadays possible to analyze not only small-scale connections and mid-size building elements, but also full...
Extreme events (i.e. terrorist attacks, vehicle impacts, explosions, etc.) often cause local damage to building structures and pose a serious threat when one or more vertical load-bearing components fail, leading to the progressive collapse of the entire structure or...
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...
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, wind,...
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,...
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 Convention and...
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...
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...
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...
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...
