摘 要：
传统的耗能支撑在强震作用后,往往产生不可修复的残余变形,给震后结构的修复和重建带来较大的困难.由于可恢复功能耗能支撑具有复位、耗能和大幅减小结构残余变形的优点,根据支撑的复位形式,分类介绍了现有不同类型的可恢复功能支撑的构造、工作原理和研究结果,并概述了现有支撑的优缺点和发展趋势.

摘 要：
The traditional energy dissipation brace often produces irreparable residual deformation under the strong earthquake, which brings great difficulty to the post-earthquake repair and reconstruction works. Various kinds of energy dissipation brace with recoverable function for its advantages of reset, energy dissipation and greatly reducing the residual deformation were proposed. This paper introduces the structural configuration, working principle and research results of different types of self-centering energy dissipation braces according to the classification of restoration forms of braces, and summarizes the advantages and disadvantages of existing braces and the development trend in the future.
