摘　　要：分析国内外RC框架试验数据,提出不考虑填充墙影响和考虑填充墙影响的RC框架结构的量化性能水准。根据所提出的量化性能水准,采用时程分析方法对一栋RC框架结构的抗震性能进行评估。分析结果表明,填充墙在弹塑性阶段仍然能够充当支撑作用,提高框架结构的整体刚度;基于时程分析法的结构抗震性能评估方法是一种可行的全面反映结构抗震性能的详细评估方法,在一定程度上弥补了现行抗震鉴定标准经验性评判的不足。Quantified seismic performance levels of pure frame and frame with infill walls were pres-ented based on test data of existing frames at home and abroad.The proposed performance levels were employed to evaluate seismic performance of an existing frame by conducting time history analy-sis.The results show that the infill walls act as diagonal trusses to enhance the stiffness of the frames even if they are in elastic-plastic state.It is confirmed that seismic performance evaluation based on time history analysis provides more detailed information than seismic appraisal of buildings,and is a more accurate and feasible method.
