The invention relates to a double-layer steel plate composite shear wall with a corrugated steel plate lateral pulling-connection resistant function, and belongs to the field of structural engineering. According to the double-layer steel plate composite shear wall, corrugated steel plates and outer side steel plates are connected together in a bolted and welded mode, then concrete is poured to form the composite shear wall, the combination in which the corrugated steel plates are welded and attached to the outer side steel plates is adopted so that lateral stiffness can be effectively providedfor the steel plate shear wall, force flow transmission of the shear wall is clearer, and the problem of insufficient lateral resistance of a giant steel plate shear wall is effectively solved; in addition, the integrally-poured concrete can improve the compression and shear bearing capacity of the steel plate composite shear wall, and buckling deformation of the outer side steel plates can be restrained; and meanwhile, the outer side steel plates provide lateral restraint for the concrete filling the interior, so that the concrete is in a bidirectional compression state, the compression resistance of the concrete is improved, and the development of concrete cracks is slowed down.

本发明涉及一种波折钢板抗侧拉结的双层钢板组合剪力墙，属于结构工程领域。由波折钢板和外侧钢板以螺栓和焊接的方式连接在一起，然后浇筑混凝土形成组合剪力墙，采用波折钢板与焊接贴合外侧钢板的组合，可有效为钢板剪力墙提供抗侧刚度，剪力墙力流传递也更为明确，有效解决了巨型钢板剪力墙抗侧能力不足的问题；此外，一体化浇筑的混凝土能提高钢板组合剪力墙的受压和受剪承载力，并能约束外侧钢板的屈曲变形；同时，外侧钢板为内填混凝土提供了侧向约束，使其处于双向受压状态，提高了混凝土的抗压能力，减缓了混凝土裂缝的开展。
