摘　　要：可恢复功能抗震结构是指地震后不需修复或者稍加修复就可恢复使用功能的结构,目前已成为地震工程领域一个新的研究方向,近年来受到了全球地震工程学者与工程技术人员的广泛关注。2017年1月在智利圣地亚哥召开的第16届世界地震工程大会的主题为"可恢复功能-土木工程的新挑战"。本文从摇摆及自复位结构、带可更换构件的结构两方面对本次世界地震工程大会展示的有关可恢复功能抗震结构的国际研究进展进行了总结。按照结构体系的不同,介绍了可恢复功能抗震结构在框架结构、剪力墙结构、框架-剪力墙结构、桥梁结构中的研究现状。大量的试验研究和数值模拟结果表明了可恢复功能结构优良的抗震性能。在此基础上,对该领域今后的研究方向进行了展望。The earthquake resilient structure is the structure which can restore the structural function immediately after a severe earthquake without significant repair, which has been a new research direction in the field of earthquake engineering, which has attracted more and more attention by the related scholars and technologists. The 16th World Conference on Earthquake Engineering was held in Santiago, Chile in the January of 2017, whose theme was ＇Resilience, the new challenge in earthquake engineering＇. In this paper the research advances in the field of earthquake resilient structures shown by this conference are summarized, focusing on the rocking and self-centering structure and the structure with replaceable components. The research progress of the application of earthquake re- silient structures in moment frame structures, shear wall structures, frame-shear wall structures, bridge structures is introduced. The results of considerable experimental study and numerical analysis have verified good seismic performance of resilient structures. Based on the above reviewing results, the research orientation and prospect in the future are discussed finally.
