Research on Material Damage Limits of RC Components for Performance-Based Seismic Design and Assessment

Abstract

This paper divided the seismic performance of RC Components into five levels: integrity, slight damage, slight ~ moderate damage and serious damage, which were defined based on material damage. Physical and mechanical description of RC components in each performance level was given, which can be used as the basis of performance-based evaluation of concrete components in microscopic model and the basis of research on deformation index limits in macro components.
