［摘要］自復位結(jié)構(gòu)體系在人們對結(jié)構(gòu)抗震性能要求日益提高和基于性能抗震設計理念的背景下獲得了大量關注。自復位結(jié)構(gòu)體系具有以下優(yōu)點：1）減小或避免主體結(jié)構(gòu)損傷；2）耗散地震能量和減小地震作用；3）最小化結(jié)構(gòu)殘余變形；4）減少震后修復費用及其間接經(jīng)濟損失。本文主要介紹了三方面的容：自復位介紹、形狀記憶合金（SMA）及其應用、PT裝置及其抗震性能、搖擺機制簡介。

Abstract： In the context of the increasing requires of structural seismic resisting and the concept of performance-based seismic design, self-centering systems have been gained lots of attention. Self-centering systems have following advantages: 1) reducing or eliminating the damage of main structure; 2) dissipating seismic energy and depressing the structural response; 3) minimizing the residual structural deformation; 4) Decreasing the cost for repair after earthquake and the indirect economic losses. Mainly four aspects were included: 1) introduction of self-centering concept; 2) application of shape memory alloy (SMA); 3) the seismic performance of post-tensioned (PT) devices; 4) brief introduction of rocking mechanism.
