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 blast, seismic events, impact, progressive collapse, and 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.
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). Learn how to model progressive collapse ten minutes or less.
Economic Performance Base Design
ELS provides an economic nonlinear dynamic structural analysis solution for use in performance based design allowing users to efficiently model and analyze structures.
Reduced Assumptions Improves Results
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.
Prevent Structural Failure
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.
Virtual Shake Table
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.
