【摘要】进行了四个整体式及四个带缝分体式空心钢筋混凝土剪力墙试件在低周反复水平荷载下的试验,研究了试件的承载力、刚度及衰减过程、延性、耗能性能、滞回特性、破坏特征、钢筋的应变情况。结果表明:整体式空心剪力墙的裂缝分布形态主要以剪切斜裂缝为主,呈现出剪切破坏形态;带缝分体式空心钢筋混凝土剪力墙以弯剪裂缝为主,呈现出延性的弯剪破坏形态;改变带缝空心钢筋混凝土剪力墙竖缝两侧暗柱配筋,可使墙体抗剪承载力不降低而其延性与变形能力得到提高。更多还原

【Abstract】 Four integral hollow RC shear wall specimens and four slit hollow RC shear wall specimens were tested under low cyclic loading to determine the carrying capacity,stiffness and stiffness attenuation,ductility,property of energy dissipation,hysteretic property,failure mechanism and strain of steel bar.Test results show that the integral hollow RC shear walls present shear failure,and mainly have shear cracks.Slit hollow RC shear walls present ductile bending-shear failure.The ductility and deformation behavior are advanced with change of steel bar of concealed column near the vertical seams,and the shear carrying capacity isn’t reduced as compared to non-slit hollow RC shear walls.更多还原
