Topic:  High Fidelity Non-Linear Structural Analysis under Extreme Loading Conditions using Extreme Loading Technology

Presentation: Video

Summary: Extreme Loading for Structures Software or ELS, is an advanced non-linear structural analysis software tool designed specifically for structural engineers. ELS allows structural engineers to study the 3D behavior of structures through both the continuum and discrete stages of loading. This includes static and dynamic loads such as those generated by a blast, seismic events, impact, progressive collapse, and the wind. Unlike many structural analysis software tools which are based on the Finite Element Method (FEM), ELS utilizes a non-linear solver based on the Applied Element Method (AEM).

This allows ELS to automatically analyze structural behavior during elastic and inelastic modes including the automatic yielding of reinforcement, detection, and generation of plastic hinges, buckling & post-buckling, crack propagation, membrane action & P-Delta effect, and separation of elements. The resulting debris and impacts with structural elements are also automatically analyzed and stress redistribution is inherently calculated.

Speaker: Ayman is a Senior Structural Engineer at Applied Science International, LLC (ASI). During his 17+ years working for ASI, he was able to develop a strong background in structural vulnerability assessment, demolition analysis, and progressive collapse analysis where he gained a lot of experience in non-linear structural analysis. Moreover, he had managed several AT/FP projects where he gained a lot of experience in this field and allowed him to publish many technical papers on progressive collapse analysis.
