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

Demand-capacity ratios pertinent to elastic response, and strength / deformation-based parameters indicative of limit state behavior and plastic response, combine with static-pushover and dynamic analysis to provide insight into where and how inelastic behavior will be achieved and advance through a structural system.

Created Analysis capabilities also extend to geometric nonlinearity and effects associated with P-Delta behavior. Advanced modeling tools enable a sophisticated simulation of structural behavior. Components may be grouped according to type, location, and limit state before evaluation proceeds in terms of strength or deformation-based demand-capacity ratio. The dynamic display of D-C usage is available through color-coordinated time-history animations.
