- The response of a structure to earthquake ground motion, whether elastic or inelastic, is highly uncertain.
- Capacity design is a rational way to improve the response of a structure in a strong earthquake, by deliberately controlling its behavior.
- Capacity design controls the inelastic behavior of a structure, by allowing inelastic behavior only in locations chosen by the designer. In these locations the structural components are designed to be ductile. The rest of the structure remains essentially elastic, and can be less ductile.
- Controlling the behavior in this way improves reliability, reduces the amount of damage, and can reduce construction costs.
- PERFORM-3D allows you to apply capacity design principles.
