摘　　要：在近些年的建筑物震害中,吊顶是破坏比较突出的一类非结构构件。首先,介绍了我国公共建筑中常见的矿棉板吊顶的基本构成,总结了矿棉板吊顶常见的破坏模式,并分析其破坏原因。其次,从试验研究、数值模拟和易损性3方面系统分析和总结了国内外关于吊顶的抗震研究进展。在试验研究方面,总结了静力试验和振动台试验两类试验的研究进展,并简要总结了振动台试验常用的加载制度。在数值模拟和易损性分析方面,从吊顶部件和吊顶整体两方面系统总结了吊顶的研究现状,指出了现有研究中存在的主要不足。最后,提出了未来在吊顶抗震研究领域可进一步开展的工作。In buildings,the suspended ceiling system(SCS)is a kind of non-structural components with obvious damage subjected to earthquakes in recent years.This paper firstly introduces the basic composition of SCS with mineral wool boards commonly used in public buildings in China,summarizes the common failure modes of this type of SCS,and analyzes the causes of failure.Then,the seismic research progress of SCSs at home and abroad is systematically analyzed and summarized in three aspects,experimental investigations,numerical simulation and fragility analysis.For experimental investigations,the research progress of static tests and shaking table tests is summarized,and the loading protocol commonly used in shaking table tests is briefly summarized.For numerical simulation and fragility analysis,the state of the art in two aspects,ceiling components and ceiling systems,is sys⁃tematically summarized,and the shortcomings in previous studies are pointed out.At last,the further work in the research field of SCSs is proposed.
