PERFORM-3D is a software useful for the performance assessment of structural systems. Stiffness and strength degradation during cyclic loading may be captured through nonlinear material modeling. PERFORM-3D has many more component-level modeling capabilities. Analysis capabilities capture [geometric nonlinearity] and display output animation-series according to useful enveloped limit-state relations.

PERFORM-3D enables users to control force-deformation relationships. Strength-based and deformation-based demand-capacity measures are closely modeled and observed for inelastic elements. Elements designed to remain elastic throughout dynamic response simplify modeling and computation in that only their linear-elastic stiffness properties need be input.

PERFORM-3D is an ideal tool for nonlinear performance-based analysis and design, created by Dr. Graham H. Powell, University of California at Berkeley Professor Emeritus of Civil Engineering.
