A double-layer steel plate composite shear wall with truss-type ties of channel members

Abstract

The invention relates to a channel-shaped piece truss type pulled double-layer steel plate combined shear wall, and belongs to the field of structural engineering. Based on the concept of improving the elastic shear buckling load of the shear wall and the shear bearing capacity of the shear wall, staggered channel-shaped pieces are innovatively introduced into the double-layer steel plate shear wall, a buckling mechanism of the wall is improved, buckling parts between adjacent wall units are staggered, the wall is changed from integral buckling to partial buckling of part of the wall units, and the possibility of integral instability of the wall is reduced; in addition, concrete is filled in the wall body, so that the compression and shear bearing capacity of the steel plate combined shearwall is improved, and the buckling deformation of outer steel plates can be restrained; and meanwhile, the outer steel plates provide lateral constraint for the inner filling concrete, so that the inner filling concrete is in a bidirectional compression state, the compression resistance of the concrete is improved, and the development of concrete cracks is slowed down.

Description

technical field [0001] The patent relates to a double-layer steel plate composite shear wall with truss-type ties of groove parts, which belongs to the field of structural engineering. Background technique [0002] With the continuous progress of our society, my country's steel output has ranked first in the world, and the steel used in the construction industry has also developed rapidly. Steel structure buildings have become an important part of my country's buildings. The steel frame-shear wall core tube structure system is more and more used in high-rise buildings due to its outstanding advantages. As an important component of the system, the shear wall can Concrete shear walls, steel plate shear walls, etc. are used. With the development of the times and scientific progress, the exploration of steel plate shear walls has received great attention. As a structural system with excellent wind resistance and earthquake resistance, the steel plate shear wall system has always...

Problems solved by technology

[0003] Due to the large overall area of ​​the shear wall, under the action of vertical load and horizontal load, it is easy to buckle as a whole and lose its bearing capacity; and because of its large area, it is difficult to mass-produce the shear force applicable to most structures wall components
