Extreme Loading for Structures Software (ELS) offers a new advanced level of nonlinear dynamic structural analysis, which allows users efficiently to study structural failure from any number of actual or possible extreme events. Unlike traditional FEM software, users can easily model high-rise structures composed of reinforced concrete, steel composite and other structures with all as-built and as-damaged details.
Extreme Loading® for Structures (ELS) software offers a new advanced level of nonlinear dynamic structural analysis, which allows users to efficiently study structural failure and retrofitting strategies in historic masonry structures from any number of possible extreme loading events including earthquake, blast, and progressive collapse.
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 is 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.
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,...read more

Model Progressive Collapse In Ten Minutes or Less:
In this short video, we take you through the process of creating a small reinforced concrete structure to illustrate how quickly you can model and analyze a detailed reinforced concrete structure for progressive collapse in Extreme Loading® for Structures Software (ELS).
ELS provides an economic nonlinear dynamic structural analysis solution for use in performance based design allowing users to efficiently model and analyze structures.
Model reinforcement, steel sections, and prestressing details commonly assumed or neglected to be fully integrated into the model with ease, providing significant improvements to the model and its results.
Applied loads are virtually unlimited and may be sequenced in a multi-hazard approach with staged loading to simulate repeated or a chain of events, including earthquakes, fire, blast, impact, tsunami, high wind, and progressive collapse.
Accelerate the research performed on shake tables with full scale virtual that can predict local and global failure, opening the door to substantial design improvements, and moving shake tables to validation, post optimization.
The Applied Element Method (AEM) based solver in Extreme Loading® for Structures is a derivative of the Finite Element Method (FEM) and the Discrete Element Method (DEM). AEM is capable of performing both linear and nonlinear, static or dynamic analysis that follows the behavior of structures through separation, collision, and collapse.
