【摘要】 在分析了现有框架—剪力墙结构的抗震性能研究的基础上,通过试验研究,比较了两片钢筋混凝土剪力墙在反复荷载作用下的强度、变形和延性性能,对剪力墙的结构以及剪切变形对剪力墙抗震性能的影响进行了分析研究。研究表明,剪力墙的剪切变形不仅与剪力墙的高宽比有关,而且与其剪应力大小和抗剪配筋有关,并提出了建议。更多还原

【Abstract】 Based on the analysing frame-wall structures and aseismic behaviour ofshear walls, with the experimental investigation of two shear walls, the sheardeformation and its effect on the aseismic behaviour of shear walls are studied by com-paring the strength、the deformation and the ductility of two specimens under cyclicloading. It is found that the shear deformation is not only related to the hight-width ra-tio,but also to the actual shear stress and the reinforcement ratio. The increase of sheardeformation makes not only shear resistant strength but also energy dissipatingbehaviour of shear walls dereased.更多还原
