PERFORM-3D is a structural engineering software useful for the performance assessment of structural systems. State-of-the-art constitutive modeling capabilities provide for characterization of strength and stiffness degradation through component-level hysteresis. Beyond material nonlinearity, geometric nonlinearity is measured through P-delta effect, often critical to prediction of structural response at life-safety and collapse-prevention performance levels.

Demand-capacity measures combine with strength-deformation controls to characterize and envelope limit-state behavior. Static-pushover and dynamic analyses provide insight into where and how inelastic behavior will be achieved and advance through a structural system.

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