填充墙对框架结构抗震性能的影响
|
摘要
针对汶川地震中框架填充墙结构的震害状况,现行2010版《建筑抗震设计规范》较2001版相比,对填充墙的重要性认识提高了一个层次,但填充墙对框架结构抗震性能的影响在规范中仍无具体的定量说明.文章分析了填充墙对框架结构抗震性能的影响,并提出了现阶段对填充墙设计和研究的两点建议:一方面填充墙框架结构的抗震设计应继续重视"概念设计"的思想;另一方面从"基于性能的结构抗震设计"的理念出发,提出了区别对待填充墙的研究思路.
In accordance with damages of the infilled wall frame structures in Wenchuan earthquake,Compared with the 2001 version of the Seismic Design Code,the current 2010 version of Seismic Design Code of Building enhanced the significance of infilled wall,but the specific quantitative instructions which refer to the infilled walls influences on seismic performance of frame structure are still absent.This paper analyzed the influence of infilled walls on seismic performance of frame structures,and put forward two suggestions on infilled wall design and research under the current phase.On the one hand,the conceptual design is supposed to be attached a great attention in infilled walls frame structure design;on the other hand,in terms of "performance-based seismic design" concept,the research conception of treating infilled walls respectively was put forward.
