摘　　要：建立结构损伤指标是用一个合理的反应量来定量反应结构的损伤,是建立结构易损性的基础性工作。此前的结构地震损伤指标研究主要集中于框架梁柱,极少有研究涉及剪力墙的地震损伤指标。考虑到高层结构中高剪跨比的剪力墙应用较广,为了研究高层结构的地震易损性,需要建立高剪跨比剪力墙的地震损伤指标。本文根据高剪跨比剪力墙的拟静力实验资料,建立了高剪跨比剪力墙的地震损伤指标,确立了剪力墙破坏程度与损伤指标值之间的关系,并对各个损伤指标的使用范围进行了讨论。The damage index is a ruler of damage performance level of structure by using a responsible parameter, which is a fundamental study to structure fragility. While the previous studies mainly focus on the seismic damage index of beams and column, few researches have studied the seismic damage index of concrete walls. Actrually, concrete walls with high span ratio is widely used in high-rise buildings, as a result, the study on seismic damage index of high-span-ratio concrete walls should be considered in order to study the seismic fragility of high-rise buildings. Based on the results of pseudo-static experiments on high-span-ratio concrete walls, this paper discussed several indexes and recommonded scope of every index on each performance level. This paper also discussed the advantages and disadvantages of each index.
