Honeycomb-shaped web crossed-section special-shaped steel column

Abstract

The invention discloses a honeycomb-shaped web crossed-section special-shaped steel column. The honeycomb-shaped web crossed-section special-shaped steel column comprises a first rectangular steel pipe flange, a second rectangular steel pipe flange, a third rectangular steel pipe flange, a four rectangular steel pipe flange, a first steel web, a second steel web and a third steel web; the first steel web, the second steel web and the third steel web are connected together to form a crossed component; the first steel web, the second steel web and the third steel web are honeycomb-shaped steel webs of which the middles are provided with web holes; each of the first steel web, the second steel web and the third steel web respectively consists of two steel plates of which the edges are provided with notches; the steel plates are welded by butt-jointed seams to form the honeycomb-shaped steel webs. According to the invention, the structural behaviors of the conventional solid-web special-shaped steel column with a crossed section and the conventional trussed web member special-shaped steel column with a crossed section are improved without obviously increasing the comprehensive cost of the construction, so that the honeycomb-shaped web crossed-section special-shaped steel column is widely applied to in the construction.

Description

technical field [0001] The invention relates to the technical field of a novel building structure, in particular to a special-shaped steel column with a honeycomb web and a cross-section. Background technique [0002] In multi-story steel structure residences, the special-shaped column structure has advantages that other structural systems cannot match. It has been highly valued and widely used. [0003] In the actual engineering of multi-story steel structure residences, the center column usually adopts the traditional solid-web cross-section special-shaped steel column or truss-type cross-section special-shaped steel column. In order to meet the requirements of compressive bending mechanical performance, a larger section size is usually required. If a solid-web cross-section special-shaped steel column is selected, the shear strength of the web will have a lot of surplus, but in order to ensure the local stability of the web, satisfy The web height-to-thickness ratio lim...

Problems solved by technology

In order to meet the requirements of compressive bending mechanical performance, a larger section size is usually required. If a solid-web cross-section special-shaped steel column is selected, the shear strength of the web will have a lot of surplus, but in order to ensure the local stability of the web, satisfy The web height-to-thickness ratio limit specified in the "Code for Design of Steel Structures" usually needs to increase the web thickness, which will lead to increased steel consumption and increased project costs, thereby increasing the overall cost of the project; if the truss type is selected In addition to the limited shear bearing capacity, seismic performance and overall stability of cross-section special-shaped steel columns, the truss-type web members need to be welded with plates or strips. The construction is relatively cumbersome, and the connection workload is relatively large. Construction cost, which also increases the overall cost of the project
