[摘要] 震后可修复性在现代基于性能的抗震设计方法研究中占有重要地位，而残余位移是评价结构可修复性的重要指标，但是传统RC结构由于其固有的缺点并不能完全满足可修复性要求。本文介绍了国内外关于残余位移的研究现状，并且介绍了几种常见的提升结构可修复性技术，其中重点介绍了正在研究的利用FRP材料提升新建建筑和已有建筑可修复性技术。

Abstract: Structures’ post-earthquake reparability occupies an very important role in modern performance-based seismic design and residual deformation is the one of the basic parameters to evaluate the reparability. However, traditional reinforced concrete structure cannot meet the reparability demands due to its intrinsic defects. This paper makes a state-of-art review about residual deformation and introduces several techniques, especially focuses on using of FRP material to enhancing reparability of both new and existing building.
