Four-side connecting open circle hole combined steel sheet shear wall

Abstract

The invention belongs to the technical field of constructional engineering, and in particular relates to a four-side connected circular hole combined steel plate shear wall, which consists of a filled-in steel plate, precast concrete slabs, frame structural members and connecting plates. The precast concrete slabs are positioned on two sides of the filled-in steel plate, and the upper end and the lower end of the filled-in steel plate are connected with the framework structural members through the connecting plates; the middle area of the filled-in steel plate is evenly distributed with circular holes, the precast concrete slabs are evenly distributed with bolt holes corresponding to the circular holes, and bolts sequentially pass through the bolt holes and the circular holes so as to make the filled-in steel plate connected with the precast concrete slabs arranged on the two sides of the filled-in steel plate; and the occupied area of the circular holes is 15 to 20 percent of the total area of the filled-in steel plate. In the invention, the four-side connected wall body is supported outside the surface by construction measures, thereby ensuring that the outside of a plane of the wall body is stable and the filled-in steel plate can effectively consume energy in violent shake. The shear wall can be widely applied in a multi-layer steel structure and a steel-concrete combined structure.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a combined steel plate shear wall with round holes connected at four sides. Background technique [0002] At present, the composite steel plate shear wall with four-sided connection is generally used in similar fields. The concrete slab of this type of composite steel plate wall has two forms, one is the integral cast-in-situ form; the other is the prefabricated slab form. The combination steel plate wall of above-mentioned two kinds of concrete slab forms all has certain deficiency. [0003] When the concrete slab adopts the cast-in-place composite steel plate wall, when it is subjected to horizontal force, the cast-in-place concrete slab will participate in the stress and deform while providing out-of-plane support for the inner filling steel plate. When the combined steel plate wall undergoes large deformation, the concrete slab may be damaged by cr...

This cannot ensure that the combined steel plate wall can effectively prevent yielding and consume energy

[0005] At present, there is no relevant patented technology that proposes a combined steel plate wall with four sides connected with round holes. With the development of high-rise steel structures in my country, especially the development of high-rise steel structure residences, the development of new lateral force-resistant structural components is also imperative.
