ELS offers a new advanced level of nonlinear dynamic structural analysis, which allows users to efficiently study structural failure and retrofitting strategies in any type of existing structures from any number of possible extreme loading events including earthquake.

Analyze and predict the boundaries of long term behavior, the relative axial stiffness and the tributary area of columns and walls, and apply the optimum distribution of additional reinforcement to reduce differential column shortening in reinforced concrete high-rise buildings.

Progressive collapse (aka: Disproportionate Collapse) occurs when a local failure spreads throughout a structure from element to element, eventually resulting in the collapse of either the entire structure or a disproportionately large part of it. Progressive collapse is caused by an abnormal or extreme loading event, typically due to accidental impact, faulty construction, foundational failure, or violent changes in air pressure (ie: Blast).

ELS offers a new advanced level of nonlinear static or dynamic structural analysis to study the behavior of structures during blast and other extreme loading events.
