Cellular connection steel plate-double-limb steel pipe concrete composite column

Abstract

The invention discloses a cellular connection steel plate-double-limb steel pipe concrete composite column, comprising a steel pipe concrete limb part 1, a steel pipe concrete limb part 2, a steel connection plate 1 and a steel connection plate 2, wherein two ends of the steel pipe concrete limb part 1 and the steel pipe concrete limb part 2 are respectively connected with each other through the steel connection plate 1 and the steel connection plate 2 to form a battened steel column; the steel connection plate 1 and the steel connection plate 2 are cellular connection plates with holes in the centers; the steel connection plate 1 and the steel connection plate 2 are respectively composed of two steel plates which are the same in shape and are provided with gaps in the edges; and the two steel plates are welded through a butt weld joint to form the cellular connection plate. According to the cellular connection steel plate-double-limb steel pipe concrete composite column, the mechanical behavior is improved, and the stability performances of a real axis and a virtual axis are fully approximate, so that the materials in the directions of two principal axes can bring into full play, the steel consumption is lowered, and the comprehensive cost of engineering is reduced.

Description

technical field [0001] The invention relates to the technical field of a novel building structure, in particular to a honeycomb connected steel plate-double-leg steel pipe concrete composite column. Background technique [0002] In recent years, the output, variety, and specifications of domestic steel and steel products have been greatly improved, and the design, manufacture, and installation of steel structures have been greatly improved. Steel structures have achieved extraordinary development in China. [0003] Due to the shortcomings of reinforced concrete columns such as heavy weight and poor crack resistance, it is difficult to meet the requirements of bearing capacity and durability, thus limiting its scope of application; while steel columns have high strength, light weight, good seismic performance, and strong deformation capacity. , short construction period, good and rich architectural artistic expression ability, etc., are generally favored by architects. In the...

Problems solved by technology

However, in actual engineering, in order not to weaken the shear capacity of the steel column too much, the "expansion ratio" of the box-shaped steel column section of the honeycomb web will be limited to a certain extent

In this case, especially for the bending column with a large bending moment, its flange may lose its bearing capacity in advance, so that it cannot meet the engineering needs
