Abstract

In recent years, in order to have a comprehensive evaluation of structural damages, quantitative methods are developed. In this regard, several research works have been done. The damage indices are based on structural drift regarding the importance and vast application of performance-based design. In this paper, the relationship between the performance levels and damage indices are studied. Several models of RC moment resisting frames were selected and analyzed using dynamic and pushover methods. Furthermore, various damage indices i.e.; Park-Ang index, stiffness index, drift index, and maximum softening and Plastic softening index for different models were estimated. Finally, the relationship between the values of these indices and the performance levels of frames is discussed in accordance with FEMA-356.
