Steel joist constrained vertical seam steel plate shear force wall

Abstract

The invention belongs to the technical field of structural engineering, in particular to a steel keel restricting steel slab shear wall with vertical seam which comprises external periphery components, an embedded steel slab with vertical seam and a stiffening rib system, wherein the external periphery components are a frame beam and a frame column, the embedded steel slab with vertical seam adopts steel with low yield point and high ductility or steel with high strength and high ductility, the stiffening rib system comprises general section material, such as a vertical stiffening rib and a horizontal stiffening rib, the embedded steel slab with vertical seam is connected with the edge frame beam through a buttcover slab, an elliptical hole which is opened on the position between the vertical stiffening rib and the buttcover slab is to provide enough sliding space for a screw bolt to penetrate, and the embedded steel slab is connected with the horizontal stiffening rib and the vertical stiffening rib through a common screw bolt. The steel keel restricting shear wall which is provided by the invention is a novel lateral force resisting component of a multiple and high rise building steel structure or other structures, which has the advantages of less slit, low cost, convenient construction and the like, and has good aseismic behavior, ductility and hysteresis energy dissipation capacity, which is a superior aseismic energy dissipating component.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to a steel keel constrained steel plate shear wall with vertical seams. Background technique [0002] Steel plate shear walls with vertical slits, as a new type of lateral force-resisting member, have been widely used in high-intensity earthquake-resistant countries such as Japan. In recent years, my country has gradually begun to study steel plate shear walls with vertical slits. Compared with concrete shear walls with vertical seams, steel plate shear walls with vertical seams have better ductility and energy dissipation capacity, and overcome the problems of concrete cracking, stiffness and ductility of concrete shear walls with vertical seams under small earthquakes. However, it is convenient for construction, flexible in design and layout, and widely applicable. It is easy to replace and repair after a major earthquake. It is a kind of seismic energy-...

Problems solved by technology

Compared with concrete shear walls with vertical seams, steel plate shear walls with vertical seams have better ductility and energy dissipation capacity, and overcome the problems of concrete cracking, stiffness and ductility of concrete shear walls with vertical seams under small earthquakes. However, it is convenient for construction, flexible in design and layout, and widely applicable. It is easy to replace and repair after a major earthquake. It is a kind of seismic energy-consuming component with superior performance; The joint ensures a small width-to-thickness ratio of the wall between the joints to prevent the out-of-plane buckling of the wall between the joints, so as to achieve better energy dissipation effect and ductility, but this increases the cost, reduces the lateral stiffness of the wall panel, and reduces the Material Utilization and Its Economy
