摘要
对两边连接钢板-混凝土组合剪力墙和两边连接钢板剪力墙进行了拟静力试验,研究了组合剪力墙在反复荷载作用下的力学性能,分析了混凝土板对组合剪力墙承载力和耗能能力的影响。采用有限元软件ANSYS分析了两边连接钢板-混凝土组合剪力墙的力学性能。研究结果表明:钢板剪力墙和组合剪力墙均表现出良好的延性;组合剪力墙中混凝土板的存在明显提高了其承载力和耗能能力,有效限制了钢板的平面外屈曲变形;在文中分析的参数范围内,当混凝土板厚度超过一定限值时能有效限制钢板的平面外变形,两边连接钢板-混凝土组合剪力墙的承载力主要与跨高比有关,随着跨高比的增加,组合剪力墙的承载力逐渐提高。
The experimental results of composite steel plate shear walls and steel plate shear walls connected to frame beams only were presented.The influences of concrete panels and height-to-thickness ratio of steel plate were studied.Meanwhile,the finite element software ANSYS was applied to develop the model.The behavior of composite steel plate shear walls was analyzed.The experimental results show that both steel plate shear walls and composite shear walls have good ductility.In composite steel plate shear walls,the concrete panels resist its out-of-plane deformation and make the steel plate shear wall work in plane.Thus the bearing capacity and energy dissipation capacity increase evidently.When the concrete panel thickness is over a special value,the out-of-plane deformation of steel plate can be fully restrained.The bearing capacity of composite steel plate shear wall mainly relies on the span-to-height ratio of steel plate.
