摘要
为研究带缝空心保温钢筋混凝土剪力墙的耗能性能,设计并制作了3组钢筋混凝土空心保温剪力墙。通过水平低周反复荷载试验,研究了该剪力墙的破坏机理、滞回特性、延性与耗能性能等力学性能,分析了竖缝形式、连接键等对空心保温剪力墙耗能性能的影响。研究表明:设置竖缝和连接键可以改变剪力墙的受力模式,使剪力墙在刚度和承载力下降较小的情况下,延性和抗震性能得到较大提高。由于耗能机理的转变,连接键、竖缝内的钢筋和橡胶带参与耗能,较大程度地提高剪力墙的耗能性能。
In order to investigate the energy dissipation capability of slit hollow heat retaining shear wall, three specimens were designed and fabricated. By cyclic lateral loading tests, failure mechanism, hysteretic characteristic,ductility and energy dissipation capacity were researched. The effect of slit style and connectors on the energy dissipation capacity was analysed. Results show： settting slits and connectors changes the mechanic mode of the shearwall. Ductility and seismic behavior was improved greatly, with slight decline of stiffness and bearing capacity. With the transformation of energy dissipation mechanism and the participation of connectors, reinforcing bars and rubber,the energy dissipation capacity of slit hollow heat retaining shear walls was increased greatly.
