| 摘 要： | 结构在强震作用下进入非线性阶段会产生不可恢复的永久位移或残余变形，结构残余位移是震后结构抗震性能和地震损失评估的重要参数，具有重要的理论意义和工程实用价值。为了深入分析残余位移的研究现状，为面向性态抗震设计和抗震韧性评估的地震动强度指标研究提供参考，全面和系统分析了国内外结构残余位移相关文献，介绍了残余位移的定义，重点论述了影响结构残余位移的主要因素，总结归纳了残余位移计算模型、残余位移控制方法及考虑残余位移的抗震性能评估方法，最后讨论了残余位移研究中存在的问题和建议。

| Abstract: | It often produces significant residual displacements when the structure enters into nonlinearity in earthquakes. The residual displacement of structures is an important parameter for the evaluation of seismic performance and loss of structures after earthquakes. It is of theoretical value and engineering significance to study the residual displacement of structures after earthquake. In order to deeply analyze the research status of residual displacement and provide references for the study of ground motion intensity measure for performance-based seismic design and seismic resilience evaluation, we firstly review the definition of residual displacement and its the main influencing factors. Then, we summarize the calculation models, the control method on residual displacement, and seismic performance evaluation method considering the residual displacement. Finally, we discuss the problems existing in the research of residual displacement and give some suggestions. |
