框架填充墙结构被动控制抗震加固分析
|
摘要
针对不满足抗震性态目标的一栋四层钢筋混凝土框架填充墙结构,基于框架和填充墙的抗震性态目标,采用附加阻尼器的被动控制方法进行抗震加固分析研究。首先,提出两种被动控制加固方案:1.在一层所有填充墙平面内方向上并联阻尼器进行抗震加固;2.在一层和二层所有填充墙平面内方向上并联阻尼器进行抗震加固;其次,基于Open Sees有限元软件,建立上述两种被动控制加固方案的有限元模型,选取El Centro、Parkfield和San Fenando三条地震动进行罕遇地震作用下的地震反应分析;最后,依据使用功能为钢筋混凝土框架填充墙结构抗震性态目标的量化指标,即综合考虑层间位移角限值和填充墙破坏情况,判定四层钢筋混凝土框架填充墙结构采用加固方案二可满足抗震性态目标的要求。
In this paper,a four- storey reinforced concrete frame infilled wall structure does not meet the seismic perform target,based on the seismic behavior target of both frame and infilled wall,to carry out the study on the passive control seismic strengthen of RC infilled wall structure with attached dampers. First,two kinds of passive control strengthen schemes were put forward. 1. Dampers were installed in the in- plane direction parallel with all 1- storey infilled walls; 2. Dampers were installed in the in- plane direction parallel with all 1- storey and 2- storey infilled walls.Then to establish the two types of passive control seismic strengthen model in Open Sees,then carry out the rare earthquake nonlinear time- history analysis under El Centro,Parkfield and San Fenando ground motions. Finally,in accordance with the seismic performance target quantization index of RC Frame infilled wall structure used,i. e. considering drift angle limit and infilled wall damage,judge the scheme 2 can meets the seismic performance target.
