16WCEE非结构构件抗震热点研究综述

A summary of hot seismic research on the nonstructural components of the 16WCEE

随着结构抗震理论的不断发展和完善,结构抗震技术已经能够满足三水准设防的性能要求,但是近年发生的数次大地震中,均表现出新的震害特征——非结构构件的严重震害。结构内部的非结构构件的严重损伤造成了巨大的经济损失和长久的功能丧失,因此非结构构件基于性态的抗震研究逐渐引起专家学者的重视。本文简要介绍了16WECC会议上投稿的有关非结构构件的论文,主要包括:非结构填充墙的研究、非结构隔震减震技术的研究以及采用楼面反应谱法计算非结构抗震性能的研究。总结了非结构构件热点研究方向并给出了未来发展趋势的建议。

With the development and improvement of the structural seismic theory, the structural seismic technology has been able to meet the requirements of the three level design principle. However, several earthquake occurred in recent years show a new damage characteristics that nonstructural components suffered serous damage. Inadequate nonstructural seismic performance has led to extensive repair costs and lengthy functional disruptions. Therefor, performance-based seismic study of nonstructural components has caught high attention of earthquake engineering researchers. Based on related research results of the 16WCEE, this paper mainly introduces the research of nonstructural infilled wall, the study of isolation technology and the discussion about floor acceleration spectra during design phase. The paper also summarizes hot research directions on the nonstructural components and points out the the developing trends in the future.
