Abstract_Chinese:本文提出一种钢管混凝土柱-横肋波纹钢板剪力墙钢结构住宅体系构成，并采用有限元模拟对于其中主要的3类剪力墙构件进行非线性推覆性能分析，研究不同类型波纹钢板剪力墙的抗侧承载能力和变形特征，并通过参数化分析探究轴压比、加劲梁布置以及钢管混凝土柱的设置方式对剪力墙抗侧性能和失效模式的影响．研究结果表明：采用加劲梁的钢管混凝土柱-横肋波纹钢板剪力墙均能在1/250层间位移角内实现弹性抗侧承载．加劲梁的设置可有效减小波纹钢板的宽度，从而降低波纹钢板的相对宽厚比，限制波纹钢板面外整体失稳，实现内嵌波纹钢板剪切屈服；一字型剪力墙在侧向变形以及轴压比较大会产生边柱的局部鼓曲和面外失稳，并诱发波纹钢板的面外失稳，导致剪力墙抗侧承载力下降，在设计时宜采用厚柱壁薄波纹板模式，且严格控制轴压比；C型和复合异形剪力墙侧面短墙肢的设置可为剪力墙提供有效的侧向支承，限制边柱整体面外失稳，增大剪力墙竖向承载力并增强其抗侧承载性能，在合理的加劲梁设置下能在1/100层间位移角内提供稳定的剪切承载能力．基于已有算例结果，在满足稳定的抗侧承载力和延性条件下，所提出的C型波纹板组合剪力墙轴压比限值可达到0.5，异形波纹板复合剪力墙轴压比可达到0.7．
Abstract_English:In this paper，a steel residential structural system with concrete-filled steel tubes and the horizontally corrugated steel plate shear wall is proposed. Nonlinear pushover analyses are performed to study the lateral resisting behaviors and deformation patterns of three primary lateral force-resisting shear walls，and then parametric studies are applied to investigate the effects of axial load ratio，stiffening beams，and arrangement of concrete-filled steel tube on the lateral resistance and failure modes. The results indicate that the proposed stiffened shear walls remain elastic lateral force bearing states within the story drift of 1/250. The stiffening beams can effectively reduce the width of the corrugated steel plate，thereby reducing the relative width-to-thickness ratio of the corrugated steel plate；restrain the out-of-plane buckling of the corrugated shear plate；and achieve the desired shear yielding at the corrugated steel plates. The planar shear wall will have local buckling and out-of-plane buckling failure at side columns under large lateral displacement or high axial loads，inducing the out-of-plane buckling of the corrugated steel plates，and this decreases the lateral load-bearing capacity of the shear wall. In the design，the mode of thick column wall and thin corrugated plate should be adopted，and the axial load ratio should be strictly controlled. The short wall limbs in the C-shaped walls and coupled walls can provide supports to the side columns，restraining the out-of-plane buckling of side columns，and then increase the vertical and horizontal load-resisting performance. With the rational design of component dimensions and stiffening beams，the C-shaped walls and coupled walls can provide a stable shear-resisting ability within 1/100 story drift. Within the analyzed models，the proposed C-shaped shear walls can provide a satisfactory lateral resisting ability and ductility under an axial ratio of 0.5，and this limit can reach 0.7 for the coupled wall.
