钢管混凝土边框内藏钢板剪力墙抗震试验与分析
|
摘要
完成了6个钢管混凝土边框钢板剪力墙抗震性能试验研究,试件包括3个不同钢板厚度的钢管混凝土边框纯钢板剪力墙和3个对应钢板厚度的钢管混凝土边框内藏钢板组合剪力墙。基于试验,分析了各试件的承载力与变形特点。采用ABAQUS软件对各试件的受力与变形特点进行了有限元分析,有限元模拟结果与试验结果符合较好。试验及分析表明:钢管混凝土边框纯钢板剪力墙具有良好的延性;钢管混凝土边框内藏钢板组合剪力墙,承载力和刚度比纯钢板剪力墙明显提高,综合抗震性能良好。
A series of tests were conducted on shear wall members in the exterior bay of a concrete filled square steel tube column(CFST) frame,which includes 3 specimens of the steel plate shear wall and 3 specimens of the embedded steel plate concrete shear wall.Testing results,including mechanical characteristics and load bearing capacities of these two kinds of shear walls,were analyzed.FEM simulation was implemented by using the software ABAQUS.The results of FEM simulation agree well with those from the experiments. The results show that the steel plate shear wall with CFST columns has good ductility.Compared with the steel plate shear wall with CFST columns,the load bearing capacity and the stiffness of the embedded steel plate concrete shear wall are improved and therefore,seismic performances of these specimens are better.
