Abstract

The invention relates to a concrete-filled steel tubular column, comprising a steel tube and truss structures. The truss structures are arranged on the inner wall of the steel tube, two or more web member ribs of each truss structure are bent in a 'W' shape, wherein first bent parts of the two or more web member ribs are connected correspondingly, second bent parts of the web member ribs are arranged on the inner wall of the steel tube at intervals, bending or inclination of a single web member rib relative to the tube wall of the steel tube is avoided, and the arrangement stability of the truss structure on the inner wall of the steel tube is improved; as for the concrete-filled steel tubular column formed after concrete is poured into the steel tube, bonding force between the concrete and the steel tube can be increased through the truss structures; and under the action of the pressure and the bending moment, the web member ribs of the truss structures can promote cooperative work ofthe steel tube and the concrete so that the tube wall face of the steel tube can be effectively restrained from externally deforming, and the local flexural property of the tube wall of the steel tube is improved. Thus the wall thickness of the tube wall of the steel tube can be further decreased, and the purposes of saving materials and lowering the cost are achieved.

Description

technical field [0001] The invention relates to the technical field of civil construction, in particular to a steel pipe concrete column. Background technique [0002] Traditional steel pipe concrete columns are generally formed by pouring concrete into steel pipes. The traditional concrete-filled steel tube columns are prone to bending deformation after being stressed. In the traditional technology, in order to ensure the overall and local stability of the CFST column, it is realized by increasing the wall thickness of the steel tube of the CFST column. However, this method leads to an increase in the steel consumption of the steel pipe, which in turn leads to an increase in cost. Contents of the invention [0003] Based on this, it is necessary to provide a concrete filled steel tube column capable of improving structural stability in order to address the above problems. [0004] A steel pipe concrete column, comprising: [0005] steel pipes; and [0006] A truss st...
