Seismic performance assessment of SRC frame structures based on component performance
Considering the deficiency of displacement-based seismic performance design,the damage degree of components is used to evaluate the seismic performance of structures in the current code.However,the proportion of damaged components at different performance levels has not been clearly specified for steel-reinforced concrete(SRC)frame structures at different performance levels.Against this background,the correspondence between the structural performances and the member properties is proposed for SRC frames,and the seismic performance evaluation method based on the component behavior of SRC frame structures is established.The incremental dynamic analysis(IDA)method was used to analyze eleven SRC frame structures with different heights and seismic intensity,and the inter-story drift ratio and component damage distribution under multiple seismic waves were discussed.According to the distribution statistics of damaged members proportion under the limit state of each performance level,the component performance indicators for evaluating the seismic performance of SRC frame structures with regular shape were established,and the seismic susceptibility analysis was adopted to evaluate the seismic performance of SRC frame structures.
