摘　　要：在碳纤维布加固混凝土十字节点和框架试件低周反复加载试验的基础上,根据原型框架实际设防要求引入能力谱方法,对采用不同碳纤维布加固方法的框架结构进行了静力弹塑性分析,对设防罕遇地震作用下加固框架的抗震性能进行评估,并作为加固设计具体量化的参考指标。According to the frames' anti-seismic requirement of Chinese building codes and the pseudo-static tests of RC interior beam-column joints and frames upgraded by CFRP sheets, the capacity spectrum analysis methods has been used in our frames including different retrofit methods of CFRP sheets to evaluate the seismic performance of strengthened frames under maximum earthquake response and give reference index for design practice.
