Corrugated web plate L-shaped section specially-shaped steel column

Abstract

The invention discloses a corrugated web plate L-shaped section specially-shaped steel column. The corrugated web plate specially-shaped steel column comprises a flat steel plate flange I, a flat steel plate flange II, a flat steel plate flange III, a steel web plate I and a steel web plate II, wherein one side edge of the steel web plate II is perpendicularly connected with the edge of the steel web plate I so as to form the specially-shaped steel column with the L-shaped section; the steel web plate I and the steel web plate II are corrugated steel web plates; the corrugated steel web plates are curvilinear, polygonal-shaped or trapezoid; the periodically repeated corrugated edges of the corrugated steel web plates are perpendicular to the length direction of a member; the non-corrugated edges of the corrugated steel web plates are respectively welded with the middle points in the width directions of the steel plate flange I, the steel plate flange II and the steel plate flange III. According to the corrugated web plate L-shaped section specially-shaped steel column, the stress performance of an existing L-shaped section specially-shaped steel column is improved, and the comprehensive manufacturing cost of engineering is not obviously increased, so that the corrugated web plate L-shaped section specially-shaped steel column can be widely applied to the engineering.

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 corrugated 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 flat-web solid-web 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 performance, larger section size, especially web size, is usually...

AI Technical Summary

Problems solved by technology

If the traditional flat-web solid-web L-shaped cross-section special-shaped steel column is selected, the shear strength of the web will be much surplus, but in order to ensure the local stability of the web, the web height and thickness specified in the "Code for Design of Steel Structures" must be met. It is usually necessary to increase the thickness of its web, which will lead to an increase in steel consumption and project cost, thereby increasing the overall cost of the project; , seismic performance and overall stability are limited, the truss-type web members need to be welded with plates or strips, the construction is relatively cumbersome, the connection workload is large, and the construction cost is increased, which also increases the overall cost of the project.
