摘　　要：结构震害指数是评价某个结构或构件在受到地震作用后的破坏状态的无量纲指数,是人们在地震后对受损建筑做出处理决策的重要理论依据。对国际上较常用的震害指数计算模型进行了简要介绍和评述,分析了这些模型的优缺点,在此基础上提出震害指数今后研究的发展方向和建议。The state-of-the-art of the research on seismic damage index in home and abroad is presented in this paper. Several kinds of seismic damage index models are reviewed and their advantages and disadvantages are analyzed and compared. Based on this, the existing problems on the research of seismic damage index and some suggestions for the future research are pointed out.

关 键 词：结构震害指数 地震作用 无量纲指数 累积损伤 滞回耗能
