Introduction

In the field of structural engineering, designing and analyzing structures that can withstand extreme loads is a critical task. Extreme Loading for Structures (ELS) is a cutting-edge software tool that enables structural engineers to study the 3D behavior of structures under various types of loads, including static and dynamic loads. In this article, we will delve into the world of ELS and explore its features, benefits, and applications.

What is Extreme Loading for Structures?

Extreme Loading for Structures (ELS) is an advanced non-linear dynamic structural analysis software tool designed specifically for practicing structural engineers. ELS allows users 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.

Key Features of ELS

ELS is equipped with a non-linear solver based on the Applied Element Method (AEM), a derivative of the Finite Element Method (FEM) and the Discrete Element Method (DEM). This allows ELS to automatically analyze structural behavior during elastic and inelastic modes, including:

Automatic yielding of reinforcement: ELS can automatically detect and model the yielding of reinforcement, which is critical in understanding the behavior of structures under extreme loads.
Detection and generation of plastic hinges: ELS can detect and generate plastic hinges, which are areas of high stress concentration that can lead to failure.
Buckling & post-buckling: ELS can analyze the buckling behavior of structures and predict the post-buckling behavior, which is critical in understanding the behavior of structures under extreme loads.
Crack propagation: ELS can analyze the propagation of cracks in structures, which is critical in understanding the behavior of structures under extreme loads.
Membrane action & P-Delta effect: ELS can analyze the membrane action and P-Delta effect, which are critical in understanding the behavior of structures under extreme loads.
