Background
Steel plate shear walls have proven to be well-behaved lateral force resistant structures that can be used in high-intensity areas and stiffened steel plate shear walls have received much attention from engineering designers because they are closer to the actual engineering of our country. The conventional stiffened steel plate shear wall is formed by uniformly welding a plurality of stiffening ribs B on two sides of a steel plate shear wall A, wherein the stiffening ribs B can be generally made of steel plates, angle steels, U-shaped steels and the like. In order to improve the processing quality, reduce the on-site welding workload and shorten the on-site construction period, the stiffened steel plate shear wall and the steel beam C at the upper part can be combined into a component for processing, wherein the steel beam C is generally H-shaped steel, as shown in fig. 1.

Because if the vertical face processing mode is adopted, the splicing of each unit is difficult, a higher platform needs to be erected for welding, and the vertical welding quality is not as good as the horizontal welding quality. However, when a horizontal machining mode is adopted, due to the existence of the stiffening ribs B, the bottom surface of the stiffening steel plate shear wall is not flat, the flatness of a machined plane needs to be calibrated and adjusted during each machining, and the size control difficulty of four edges is high. Meanwhile, the width of the steel beam C flange on the stiffened steel plate shear wall is generally greater than the height of the stiffening rib B, so that when the stiffened steel plate shear wall is placed on a conventional platform, the bottom fulcrums of the stiffened steel plate shear wall are different in height, and a plane is difficult to form.
