Inclined double-layer folded plate steel plate shear wall

Abstract

The invention relates to a building member and in particular relates to an inclined double-layer folded plate steel plate shear wall. Framework columns and framework beams are connected into a square framework, an inner filler plate connected with the framework columns and the framework beams is arranged in the framework, the framework columns comprise a first framework column and a second framework column which are parallel to each other, the inner filler plate is in a folded plate structure, the included angle between the length direction of a groove and the column direction of each framework column is 30 degrees-60 degrees, and the inner filler plate is a trapezoidal, V-shaped or groove-shaped folded plate and can directly adopt a profiled steel plate. Another structure of the shear wall provided by the invention is as follows: the shear wall adopts two inner filler plates, the two inner filler plates are obliquely and crosswise arranged, the effects are better, and the shear wall can be used for overcoming the defects that the thin steel plate shear wall can not fully play strength and tensility roles of steel due to early buckling, improving the out-of-plane stability and bearing capacity of the steel plate shear wall, fully playing the advantage of high tensile strength of the steel, effectively solving the problem of overall instability and reducing the steel consumption and has the characteristics of high stability and low cost.

Description

technical field [0001] The invention belongs to the technical field of building components, and relates to a horizontal force-resisting component in a multi-high-rise steel structure building, in particular to an inclined double-layer folded plate steel plate shear wall. Background technique [0002] By studying the earthquake damage data at home and abroad, it is found that the multi-story structure with Steel Plate Shear Wall (SPSW for short) has a good ability to resist lateral force, and the earthquake has little damage to the main stressed components. As the main lateral force-resisting member, the steel plate shear wall has been widely used in the multi-story steel structure system. It not only has a large initial lateral stiffness, but also has a good energy dissipation capacity. For such a high-rise lateral force resistance system with broad development prospects, the research work on it has never stopped, and good results have been obtained. [0003] The buckling c...
