Displacement Based Design
* Traditionally, earthquake-resistant design has been strength-based, using linear elastic analysis.
* Since inelastic behavior is usually allowed for strong earthquakes, this is not entirely rational.
* Strength-based design considers inelastic behavior only implicitly.
* Displacement-based (or deformation-based) design considers inelastic behavior explicitly, using nonlinear inelastic analysis.
* Displacement-based design recognizes that in a strong earthquake, inelastic deformation (or ductility) can be more important than strength.
* PERFORM-3D allows you to use displacement-based design.
Implementation of ASCE 41
* Procedures for displacement-based design using inelastic analysis are specified in ASCE 41, “Seismic Rehabilitation of Existing Buildings”.
* ASCE 41 applies to the retrofit of existing buildings, but the procedures can be applied to the design of new buildings.
* PERFORM-3D implements the procedures in ASCE 41.
* However, PERFORM-3D is a general tool for implementing displacement-based design. It is not limited to ASCE 41.
