The invention relates to an inner stiffened double-steel-plate shear wall giving consideration to load bearing and energy consumption. The inner stiffened double-steel-plate shear wall comprises double steel plates and an edge member, and the edge member comprises edge columns and edge beams, First stiffening ribs are arranged in the double steel plates at a certain distance to form the box type steel plate shear wall, the out-of-plane rigidity of the steel plate shear wall is greatly improved through the section form, the double-steel-plate shear wall has the capacity of bearing vertical loads without premature out-of-plane buckling, under the action of horizontal force, inner stiffened ribs limit out-of-plane bulging deformation of the double steel plates, the out-of-plane rigidity of the steel plate shear wall is improved, so that the double-steel plate shear wall has the capacity of bearing vertical loads, buckling deformation is restrained through the first stiffening ribs and the double steel plates, the pinching phenomenon of a hysteretic curve is effectively prevented and improved, meanwhile, the defects that when the buckling restrained steel plate shear wall is connected with reinforced concrete cover plates on the two sides through split bolts, the embedded steel plates are weakened, the energy dissipation capacity is affected, and the construction technology is complex are overcome.
本发明涉及一种兼顾承重和耗能的内加劲双钢板剪力墙，包括双钢板和边缘构件，所述边缘构件包括边缘柱和边缘梁；双钢板分开一定的距离内置第一加劲肋形成箱型钢板剪力墙，该种截面形式大大的提高了钢板剪力墙的面外刚度，使得该种双钢板剪力墙具有承担竖向荷载的能力而不过早的发生面外屈曲，在水平力作用下，内加劲肋限制双钢板的面外鼓曲变形，提高了钢板剪力墙的面外刚度使得该种双钢板剪力墙具有承担竖向荷载的能力，同时利用第一加劲肋与双钢板互相约束屈曲变形，效防改善了滞回曲线的“捏缩”现象，同时克服了屈曲约束钢板剪力墙通过对拉螺栓连接两侧钢筋混凝土盖板时削弱内嵌钢板影响耗能能力及施工工艺复杂的缺点。
