摘要
为了研究带缝空心钢筋混凝土剪力墙结构的抗震性能,本文进行了六层1/3.0比例模型房屋的拟动力及拟静力试验,分析了带缝空心钢筋混凝土剪力墙结构在地震作用下的变形与耗能性能,探讨了结构在地震作用下的破坏机理、滞回特性及其薄弱环节或部位。试验结果表明:该结构模型延性的弯剪破坏形态与普通钢筋混凝土剪力墙结构不同;竖缝的设置增加了结构在弹塑性阶段的变形及耗能能力,结构具有较强的变形及耗能能力。作为一种抗震性能良好的新型的结构形式,带缝空心钢筋混凝土剪力墙结构具有一定的工程推广应用前景。
In order to study the aseismatic property of reinforced concrete hollow shear wall structure with slits,pseudo-dynamic and pseudo-static tests on a 1/3.0 scale six-storey model building were conducted.Property of deformation and energy dissipation capacity of the structure under seismic action were analyzed,with emphasis on damage mechanism,hysteretic property and weak points or parts of structure.Experimental results show that the ductile bending-shear failure mode of the structure is different from that of common shear wall;the deformation capacity and energy dissipation property of the structure were greatly improved because of the vertical seams in the model structure in elastic-plastic behavior,and the model structure has strong capacity of deformation and energy dissipation.As a new kind of structure with good aseismatic property,reinforced concrete hollow shear wall structure with slits is worthwhile to be widely applied and popularized in actual engineering.
