Box-section column of corrugated steel web-concrete filled steel tube flange combination

Abstract

The invention discloses a box-section column of a corrugated steel web-concrete filled steel tube flange combination. Two webs and two flanges are connected to form a box-shaped structure, wherein the webs are corrugated steel webs; the periodically repeated corrugated edges of the corrugated steel webs are perpendicular to the length direction of a component; the non-corrugated edges of the corrugated steel webs are welded to the two width ends of the flanges; the flanges are concrete filled steel tube flanges including steel tubes and concrete in the steel tubes; the concrete is self-compacting concrete. According to the box-section column of corrugated steel web-concrete filled steel tube flange combination disclosed by the invention, the structural behavior of the box-section column of existing flat webs is improved and the comprehensive cost of the project is not increased significantly, so that the box-section column of corrugated steel web-concrete filled steel tube flange combination can be applied widely in projects.

Description

technical field [0001] The invention relates to the technical field of a novel building structure, in particular to a corrugated steel web-steel tube concrete flange composite section box-shaped column. Background technique [0002] The multi-high-rise steel structure is becoming more and more prominent in my country's modernization construction, and is more and more favored by people. In recent years, it has been highly valued by scholars and engineers at home and abroad, and has been widely used. [0003] In the actual engineering of multi-story steel structures, especially when the load is large or the torsional requirements of the components are high, or the surface of the components is required to be flat or closed, the traditional flat-web box-section steel columns are usually used, and Its cross-sectional dimensions are usually large, especially the web dimensions. In order to ensure the local stability of the web and meet the web height-to-thickness ratio limit spec...

Problems solved by technology

No matter which scheme is adopted, it will lead to an increase in steel consumption and construction cost, thereby increasing the overall cost of the project

Moreover, when the bending moment effect is large, the flange of the steel column may enter the failure state prematurely, causing the steel column to quickly lose its resistance; at the same time, the steel column is a pure steel structure, and its fire resistance is poor
