Stiffness and strength degradation during cyclic loading may be captured through [nonlinear material|kb:Material nonlinearity] modeling. PERFORM-3D has many more component-level modeling capabilities. Analysis capabilities capture [geometric nonlinearity|kb:Geometric nonlinearity] and display output animation-series according to useful enveloped limit-state relations. \\ *PERFORM-3D* users have control over 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|kb:Nonlinear] performance-based analysis and design, created by Dr. Graham H. Powell, University of California at Berkeley Professor Emeritus of Civil Engineering. |
