The main objective of this research is to develop a practical damage criterion based on pushover analysis. For this purpose, damage analysis is performed on several Reinforced Concrete Moment Resisting Frames (RCMRFs). In the static method, performance point of structures is firstly determined using capacity spectrum method and then values of several different damage indices are calculated at these points. By comparing the results of two methods and evaluating correlation between two sets, explicit damage relations are derived based on the static results
