【摘要】 在单调和低周反复荷载作用下进行4榀1/3～1/4缩尺模型的中高混凝土剪力墙的对比试验,包括1榀普通钢筋、1榀内置型钢框架和2榀内置型钢桁架.结果表明,带型钢内置框架剪力墙的耗能能力远优于纯钢筋混凝土剪力墙,斜向支撑使试件的抗震能力进一步提高;与纯钢筋混凝土相比,型钢支撑框架混凝土剪力墙的极限荷载提高约25%,极限位移提高约29%,耗能提高约36%;内置型钢框架和型钢桁架可不同程度地提高普通剪力墙的后期刚度,减小墙体的层间位移,改善墙体的破坏形态.更多还原

【Abstract】 Monotonic and cyclic lateral load tests on four 1/3～1/4 scale mid-rise concrete shear wall specimens are performed,including one piece of common steel reinforced concrete shear wall,one piece of concrete shear wall embedded with steel shape frame and two pieces of concrete shear wall embedded with steel shape truss.The concrete wall embedded with steel shape frame shows much better performance in energy dissipation than that of common steel reinforced concrete shear wall.The wall embedded with steel shape truss can further enhance the seismic behavior.Contrast with the common steel reinforced concrete shear wall.The concrete shear wall embedded with steel shape truss can increase about 25% in ultimate load,29% in limit displacement and 36% in energy dissipation capacity and perform much better in rigidity,inter-story drift ratio and damage shape than others.Overall,the wall embedded with steel truss show best behavior in seismic resistance.更多还原
