Nonlinear Static Analysis

Pushover AnalysisNonlinear static analysis, commonly referred to as pushover analysis, is a method for determining the ultimate load and deflection capability of a structure.  Local nonlinear structure effects, such as flexural hinges at the member joints, are modeled and the structure is deformed or "pushed" until enough hinges form to develop a collapse mechanism or until the plastic deformation limit is reached at the hinges.
