Honeycomb-shaped web special-shaped steel column with L-shaped section

Abstract

The invention discloses a honeycomb-shaped web special-shaped steel column with an L-shaped section. The honeycomb-shaped web special-shaped steel column comprises a first plain steel plate flange, a second plain steel plate flange, a third plain steel plate flange, a first steel web, a second steel web and holes; one side edge of the second steel web is perpendicularly connected with the edge of the first steel web, and the other side edge of the second steel web and two side edges of the first steel web are respectively connected with the first plain steel plate flange, the second plain steel plate flange, the third plain steel plate flange together to form the special-shaped steel column with the L-shaped section; the first steel web and the second steel web are honeycomb-shaped webs of which the middles are provided with the holes; each of the first steel web and the second steel web respectively consists of two steel plates of which the edges are provided with notches and the shapes are the same; every two corresponding steel plates are welded by a butt-jointed seam to form one honeycomb-shaped web. According to the invention, the structural behaviors of the conventional solid-web special-shaped steel column with an L-shaped section and the conventional trussed special-shaped steel column with an L-shaped section are improved, and the comprehensive cost of the construction is controlled.

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 an L-shaped cross-section of a honeycomb web. Background technique [0002] In the modern construction of multi-high-rise steel structure residences, the advantages of special-shaped column structures have become more and more prominent, and their status has become increasingly prominent. In recent years, they have been highly valued by academic circles and engineering technicians at home and abroad. The application is also more and more extensive. [0003] In the actual engineering of multi-story steel structure residences, the corner columns usually adopt traditional solid-belly L-shaped cross-section special-shaped steel columns or truss-type L-shaped cross-section special-shaped steel columns. In order to meet the requirements of compressive bending mechanical performance, a larger cross-sectional size is usually required...

AI Technical Summary

Problems solved by technology

In order to meet the requirements of compressive bending mechanical performance, a larger cross-sectional size is usually required. If a solid-web L-shaped 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 L-shaped cross-section special-shaped steel column, in addition to its limited shear bearing capacity, seismic performance and overall stability, its truss-type web members need to be welded with plates or strips, the construction is relatively cumbersome, and the connection workload is relatively large, which increases the Construction cost, which also increases the overall cost of the project
