地震可恢复性与非结构系统性态抗震研究略述

A review of seismic resilience and performance-based seismic study of nonstructural systems

地震可恢复性研究已成为地震工程学和防灾减灾领域的细化深化热点研究方向,与之相关的非结构系统抗震性能决定了工程建筑的功能性水平,是地震可恢复性研究的重要关键环节,已受到广大地震工程研究人员的高度关注。围绕16WCEE会议发表的相关研究成果,本文介绍了地震可恢复性的基本概念及其发展演变、建筑设施及社区地震可恢复性概念与框架的研究进展,对地震可恢复性评价方法、与之相关的各类非结构系统构件性态抗震评估与试验方法、设计方法与抗震装置的最新研究成果进行了梳理总结,对地震可恢复性以及相关联的非结构系统性态抗震研究发展方向提出了建议。

Seismic resilience research has become a detailed and deepening hot point in the field of earthquake en- gineering and disaster prevention and mitigation. As the relevant seismic performance of nonstructural systems could decide the functional level of engineering construction, performance-based seismic study of nonstructural systems can be the key point of seismic resilience research, which has also caught high attention of earthquake engineering researchers. Based on related research results published in 16WCEE meeting, this paper introduces basic concept and development of seismic resilience, and research advance of concept and frame of both building facilities and community seismic resilience. The paper also summarizes latest research findings on the evaluation methods of seismic resilience and related nonstructural systems, and the test/design methods and seismic devices of nonstructural components. The research directions of both seismic resilience and associated performance-based seismic study of nonstructural systems are finally proposed.
