摘要：In the current structure damage assessment process, different methods of selecting damage index threshold will significantly affect assessment results. OpenSees finite element software is used to build a 6-story RC frame structure model. Then, the inter-story drift and residual inter-story drift are used as single and double indices to calculate threshold values using the code method and the incremental dynamic analysis method. Evaluation results vary more significantly when the damage is evaluated using a single index. When the threshold is selected based using the code method with a double index, the results are more conservative. The stronger the correlation between the inter-story drift and residual inter-story drift is, the more conservative the results are.
