Steel plate built-in eccentric support type steel plate shear wall

Abstract

The invention provides a steel plate built-in eccentric support type steel plate shear wall. The steel plate built-in eccentric support type steel plate shear wall comprises a rectangular frame which is formed by sequentially connecting a left frame column, an upper frame beam, a right frame column and a lower frame beam, wherein an internally-filling steel plate in a shape of rectangle is connected with the middle of the rectangular frame through an inclined support, and positioned at the centre of the rectangular frame; horizontal supports are arranged at the upper and lower edges of the internally-filling steel plate; and upright supports are arranged on both sides of the internally-filling steel plate. The steel plate built-in eccentric support type steel shear wall solves the problems that the floor is extremely damaged due to the suddenly-reduced structural rigidity and energy consumption performance and excessively high plastic deformation at an energy consumption beam section of an eccentric supporting structure caused by the bending of the frame supporting structure; the steel plate built-in eccentric support type steel shear wall integrates the advantages of the eccentric support and the steel plate shear wall system, and can meet the requirement on normal use, and also can improve the lateral resisting rigidity and the energy consumption performance of the structural system; and the steel plate built-in eccentric support type steel plate shear wall fully implements the advantages of steel, reduces the quantity of used steels, and brings good economic benefits.

Description

Technical field [0001] The invention belongs to a horizontal anti-side force component in a multi-high-rise steel structure building, and specifically relates to an eccentrically supported steel plate shear wall with built-in steel plates. Background technique [0002] In recent years, the rapid development of multi-high-rise buildings in my country and the continuous increase in building heights require high-rise structures to have sufficient lateral stiffness to resist the horizontal load of the structure. my country's "Technical Regulations for Steel Structures of High-Rise Civil Buildings" (JGJ99-98) stipulates that the seismic structure system should be equipped with multiple seismic defense lines, and the loss of seismic capacity of the entire system due to damage to some structures or components should be avoided. A single lateral force system cannot meet the seismic fortification requirements of multi-high-rise buildings, while the dual lateral force system—frame support ...

Problems solved by technology

[0004] In order to overcome the above-mentioned shortcomings of the prior art, the object of the present invention is to provide an eccentrically supported steel plate shear wall with built-in steel plates. Excessive plastic deformation of energy-dissipating beams in the structure causes large damage to the floor. By absorbing the resp
