Nonlinear 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. |
