砖填充墙钢筋混凝土框架拟动力地震反应试验及理论分析

Pseudo-Dynamic Earthquake Response Test and Theoretical Analysis of RC Frame with Brick Masonry Infilling

本文通过二个１：２．５缩尺的无门洞砖填充墙和开门洞砖填充墙框架的拟动力地震反应试验，研究了砖填充墙框架结构模型在弹性、开裂和破坏各个阶段的地震反应和破坏形态，并与纯框架的拟动力地震反应试验结果进行了比较。采用杆系－层间模型进行无门洞砖填充墙框架的弹塑性地震反应分析，计算结果表明，理论分析结果与试验结果吻合较好。

Through the pseudo-dynamic tests of two 1:2.5 scale models of the brick masonry infilled prototype reinforced concrete frames with and without opening,their earthquake responses in the elastic stage,inelastic stage and failure stage and failure modes have been studied.The results are compared with those of the frame without any infilling tested by the pseudo-dynamic method.The bar element-story calculation model has been used for comparison as to its elastic,inelastic and collapsing earthquake responses analysis.It is indicated that the measured And calculated time-dependent curves of displacement are in good agreement
