Abstract

The ability of a structure that has experienced an earthquake to withstand the next earthquake is estimated by damage index. There are several damage indices that have been proposed by researchers to quantify the amount of damage to the structure. These are generally defined based on dynamic response of structure and its hysteretic characteristics. Due to time consuming and complicated process of nonlinear dynamic analysis and calculation of damage index via these methods, in this paper using a pushover analysis and employing the stiffness damage index, the deterioration of the stiffness of the structure in various performance levels is evaluated. The obtained results are compared to that of qualitative definitions of FEMA. For this purpose a computer program has been prepared that considering earthquake specifications and characteristics of any structure, automatically evaluates the damage in RCMRF in various performance levels. Eight samples of RCMRF that had been designed based on ABA and Iranian Standard No. 2800 and one sample that was designed based on FEMA for four performance levels were evaluated for damage and discussed on. The results of evaluations show that the proposed damage index can be a proper criterion for seismic performance evaluation of RCMRF. According to the results it seems that the criterion of drift in, FEMA and ATC, alone cannot be a correct and perfect criterion for performance and damage of structure.
