Bending restraining type shear wall with slideable stiffening shaped steel and internally embedded steel plate

Abstract

The invention provides a bending restraining type shear wall with a slideable stiffening shaped steel and an internally embedded steel plate, belonging to the technical field of structural engineering. The shear wall consists of the internally embedded steel plate, a stiffening rib of the shaped steel, a fishplate and an edge component. The internally embedded steel plate adopts a thin steel platerolled by high-extensibility steel material; the edge component consists of an edge pillar and an edge beam; the stiffening rib of the shaped steel adopts the shaped steel in the forms of an I-shape,a box shape, a C-shape, an L-shape, a brim-curling shape or the other sections; the internally embedded steel plate is provided with arc notches at a quarter of four corners; the internally embeddedsteel plate is connected with the edge component by the fishplate; and the internally embedded steel plate is connected with the stiffening rib of the shaped steel with a high-intensity bolt which penetrates therethrough. The bending restraining type shear wall with the slideable stiffening shaped steel and the internally embedded steel plate can be taken as a novel lateral force-resistant component of a high rise building steel structure or other structures of the novel lateral force-resistant components, has the advantages of good earthquake-resistant performance, high extensibility, convenient construction and cost saving, and is a predominant earthquake-resistant energy-dissipating component.

Description

technical field [0001] The invention relates to a buckling-inhibited shear wall in which stiffened steel and embedded steel plates can slide, and belongs to the technical field of building structure engineering. Background technique [0002] In the structural design of high-rise buildings, the steel plate shear wall is a new type of lateral force-resisting structural system. Because it belongs to the same material as the steel frame structure, it shows the same ductility and energy dissipation capacity when resisting earthquake action. [0003] Although the thick steel plate shear wall is not easy to buckle and has a good hysteretic energy dissipation curve, it consumes a lot of steel and has poor economic benefits, so it is difficult to be accepted by the market. At the same time, due to the limitation of buckling of the steel plate wall, it is difficult for engineering designers to intentionally change the lateral stiffness in a certain direction by adjusting the thicknes...

Problems solved by technology

However, arranging a whole concrete slab on both sides of the embedded steel plate also brings new problems. First, the appearance of the concrete slab greatly increases the mass of the structure itself, which stimulates a new earthquake action. The cost of concrete cover slabs is greatly increased. This is because the general wall scale is relatively large (the height is about 3 meters, and the width is often more than 6 meters). A large internal force must be generated inside a whole concrete slab. The tensile strength of the plate is low, and it is a bending member when it is subjected to the outward bending force of the embedded steel plate, and the tensile stress is mainly generated on its section, which is not conducive to exerting the strength of the concrete material

Therefore, only by increasing the thickness of the concrete slab in the design can the purpose of restraining the buckling deformation of the embedded steel plate be achieved, so the economic benefit is very low
