*PERFORM-3D* is a sophisticated modeling and analysis software useful for the performance assessment of structural systems. PERFORM-3D offers a range of capability for the modeling of component-level [force-deformation|kb:Material nonlinearity] relationships. Strength and stiffness degradation may be characterized for cyclic response. Another notable feature is the output animation which displays enveloped limit-state relations. 

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