摘　　要：为准确评估砌体结构震后损伤,采用能量分析的塑性耗能作为衡量指标,将剩余抗震能力指数R作为砌体结构震后损伤评估指标,利用ABAQUS软件对不同损伤等级的震损砌体结构进行动力弹塑性分析。结果表明,损伤等级为基本完好、轻微破坏、中等破坏、严重破坏等级的剩余抗震能力指数范围分别为[1.00~0.95)、[0.95~0.70)、[0.70~0.49)、[0.49~0.00),毁坏不再考虑,默认为0。文中方法得到的R值与国际已有标准基本吻合,证明了该方法的有效性。This paper is aimed at the accurate evaluation of post-seismic damage to masonry structures.The study is performed by taking plastic energy consumption of energy analysis as the measurement indicator,using the remaining seismic resistance index R as the post-seismic damage assessment indicator for masonry structures,and using ABAQUS softwar to perform a dynamic elastic-plastic analysis of the seismic masonry structures at different damage levels.The results show that based on the damage levels at basically intact,minor damage,moderate damage,and serious damage,the residual seismic ability index ranges present[1.00-0.95),[0.95-0.70),[0.70-0.49),and[0.49-0.00),respectively,with no regard to destruction by 0 default.The obtained R value is basically consistent with existing international standards,proving that this method is effective.
