Side column connecting node of thin steel plate shear wall

Abstract

The invention relates to a side column connecting node of a thin steel plate shear wall, belonging to the field of building structure engineering. The side column connecting node of the thin steel plate shear wall comprises the thin steel plate shear wall and a round steel tube concrete side column (1), and is characterized in that one end of a connecting steel plate (2) is connected with the side vertical through length of the thin steel plate shear wall, and the other end thereof is inserted into the round steel tube concrete side column (1); the connecting steel plate (2) is welded with the round steel tube concrete side column (1) at the side wall crossing part; an anchoring steel plate (3) is vertically inserted into the round steel tube concrete side column (1) along the longitudinal direction, and is welded with the connecting steel plate (2) in a vertically crossing way. The side column connecting node leads the circular hoop function of the round steel tube concrete side column to be still fully exerted, and does not change the bearing capacity of the round steel tube concrete side column.

Description

technical field [0001] The invention belongs to the field of building structure engineering, and in particular relates to a wall column connection node in a thin steel plate shear wall. Background technique [0002] The steel plate shear wall structure is a new type of lateral force resistant member structure system developed in the 1970s. With the research of steel plate shear walls, the currently used steel plate shear walls are divided into thick steel plate shear walls and thin steel plate shear walls. According to the current research, the mechanical mechanism of thick and thin steel plate shear walls is mainly distinguished according to whether the post-buckling strength of the steel plate is used. The thick steel plate relies on the shear stiffness of the steel plate to resist the horizontal force, and the steel plate remains elastic all the time. This design prevents the actual strength of the steel plate from being fully utilized, while the thin steel plate utilize...

AI Technical Summary

Problems solved by technology

[0003] At present, the thin steel plate shear wall is directly welded to the circular steel tube concrete side column. Under the horizontal load such as wind or earthquake, the thin steel plate shear wall will generate a unidirectional tensile force on the circular steel tube concrete side column wall at the connection node. , the tensile force will cause the steel pipe wall to be partially tensioned and deformed, resulting in the weakening of the steel pipe wall's hoop effect on the three-dimensional stress, resulting in a reduction in the bearing capacity of the steel pipe concrete
