Abstract

Abstract

Restoring force model plays a very important role in the research of earthquake -resistant structure. Taking thedeformation and internal force of a section as generalized stress -strain, utilizing plastic potential theory and flow rule as wellas hardening model and concrete yield criterion, it is induced the relation between force and deformation of frame columns(the skeleton curve of restoring force model). The choice of equation parameters and their identification are discussedaccording to the building code, and it is proved that the model agrees with the test resultswell.
- restoring force,
- skeleton curve,
- plastic potential theory
