Steel plate shear wall

Abstract

The invention discloses a steel plate shear wall comprising an upper edge frame beam, a lower edge frame beam, a first frame column, a second frame column, a perforated steel plate, an upper end steel angle and a lower end steel angle. The upper edge frame beam, the lower edge frame beam, the first frame column and the second frame column form a frame structure. The perforated steel plate, the upper end steel angle and the lower end steel angle are disposed inside the frame structure. The upper end of the perforated steel plate is sequentially connected with the upper end steel angle and the upper edge frame beam. The lower end of the perforated steel plate is sequentially connected with the lower end steel angle and the lower edge frame beam. The steel plate shear wall has good earthquake resistance, ductility and dissipation capacity, the perforated area of the steel plate can yield over full section area, availability of the steel plate can be improved, seam end stress concentration can be suppressed effectively, and the steel plate shear wall is an excellent energy dissipation component.

Description

technical field [0001] The invention belongs to the field of structural engineering, and in particular relates to a steel plate shear wall with laterally stiffened and diamond-shaped holes connected at both sides. Background technique [0002] Since the steel plate shear wall with vertical slits was proposed as a new type of lateral force-resisting member at the beginning of this century, it has been widely used in Japan and other high-intensity seismic fortification countries. In recent years, the steel plate shear wall with slits has also begun to be applied in my country. . This type of lateral force-resistant component has good ductility and energy dissipation capacity, and has the advantages of convenient construction, flexible layout, and convenient maintenance and replacement after a major earthquake, making it an anti-seismic energy-consuming component with superior performance and broad application prospects. However, in the course of the research, it was found that...

Problems solved by technology

However, in the course of the research, it was found that in the traditional steel plate shear wall with vertical slits, only the two ends of the wall between the slits form plastic hinges, and most of the steel plate is still in the elastic stage, although it has a good energy dissipation capacity. , but the utilization rate of the steel plate is not high and the stress concentration is more obvious even if the joint end adopts a circular arc transition. Therefore, the present invention proposes a steel plate shear wall with two sides connected laterally stiffened with diamond-shaped holes. This type of lateral force-resistant member is rationally designed. It can realize the full cross-section yield of the wall pier between the steel plate shear wall holes, improve the utilization rate of the steel plate, increase its economy and effectively suppress the stress concentration at the end of the joint
