Double-channel beam concrete combination column

Abstract

The invention discloses a double-channel beam concrete combination column which comprises a combination column and a steel bar frame, wherein the steel bar frame is arranged in the concrete column and is composed of longitudinal steel bars and stirrups which encircle the longitudinal steel bars horizontally, and the longitudinal steel bars are respectively evenly distributed on the inner wall of the steel bar frame along the longitudinal depth direction of the steel bar frame. A structural steel framework is arranged in the steel bar frame, and the structural steel framework is formed by connection of a steel web and double-channel beam steel, the steel web is arranged in the middle of the double-channel bar steel, the steel web is perpendicular to a web of the double-channel beam steel, channel beam flanges are symmetrically arranged on two sides of the web of the double-channel beam steel, and the two pairs of channel beam flanges are respectively connected through batten plates. The binding effect of structural steel to core concrete is improved through a reasonable steel matching manner of the double-channel beam concrete combination column, cooperative work of the structural steel and the concrete is ensured, and therefore the purpose of improving the bearing capacity and anti-seismic property of the column is achieved.

Description

technical field [0001] The invention relates to a steel-concrete composite structure and an SRC column of a mixed structure, in particular to a double-channel steel-concrete composite column. Background technique [0002] The steel-concrete structure is an embedded composite structure system that is filled with concrete, and is called SRC structure for short. The steel reinforced concrete column is an important part of the steel concrete structure. At present, the steel reinforced concrete column mainly adopts several steel forms such as I shape, H shape and core cross. The test shows that the seismic performance of the steel concrete column is improved compared with the ordinary RC column. However, with the deepening of engineering application and research, the limitations of the traditional form of steel-concrete columns currently used are clearly reflected. The traditional form of steel distribution has a poor confinement effect on the core concrete of the column section...

However, with the deepening of engineering application and research, the limitations of the traditional form of steel-concrete columns currently used are clearly reflected

The traditional form of steel distribution has a poor confinement effect on the core concrete of the column section, and the slippage between the steel and concrete reduces the bearing capacity and deformation capacity of the column. In this case, the ductility of the steel concrete column is poor, and the axial compression ratio The limit value is low, the seismic performance is not much improved compared with ordinary RC columns, and the scope of application is limited
