框架-稀疏框格复合墙抗剪承载力计算方法研究
|
摘要
为了增强框架结构和底部框架砌体结构的抗震性能,提出在框架内部设置稀疏框格复合墙形成组合式抗震墙的方法,并对该组合式抗震墙抗剪承载力计算方法进行研究。首先对两片1/2比例框架-疏格复合墙进行低周反复荷载试验,分析了试件的抗剪试验结果及滞回曲线特点;在试验研究的基础上,结合已有框架格构剪力墙、构造柱-芯柱砌体墙等相关试验资料,分析了框架-疏格复合墙的受力特点及抗剪机理,提出了框架-疏格复合墙抗剪承载力的通用计算公式,并给出了不同条件下公式的使用方法。计算结果与试验结果的对比表明,本文建议公式具有较好的计算精度,可供框架结构、底部框架砌体结构的新建或震后重建参考。
In order to enhance the seismic performance of the frame structure and masonry structure with frame at bottom layer,combined shear wall consisting of frame and gridiron composite wall was proposed,and the shear bearing capacity calculation method for the wall was researched.1/2 scale frame-sparse gridiron composite walls were tested under reversed cyclic loading.Damage processes,load-bearing capacity and hysteretic curves characters of the walls were analyzed.Based on the experiments and reinforced concrete masonry walls data,the force features and shear resistance mechanism of the wall were analyzed,the general shear bearing capacity formula and its application under different conditions were put forward.Comparative analysis between calculation results and test results indicated that the formula was accuracy enough,and can be referred in frame structure or masonry structure with frame at bottom layer.
