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

Abstract

The invention discloses a honeycomb-shaped web special-shaped steel column with a T-shaped section. The honeycomb-shaped web special-shaped steel column with the T-shaped section 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 middle part 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 T-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 steel plates of which the edges are provided with notches; the steel plates are welded by butt-jointed seams to form the honeycomb-shaped webs. According to the invention, the structural behavior of the special-shaped steel column is improved without obviously increasing comprehensive cost of the construction, so that the special-shaped column structure is more widely applied to multi-storey and high-rise residences.

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 T-shaped cross-section of a honeycomb web. Background technique [0002] In residential buildings, special-shaped column structures have incomparable advantages over other structural systems, and are more and more favored by people. In recent years, they have been highly valued by scholars and engineers at home and abroad, and thus have been widely used. [0003] However, in multi-story residential buildings, the reinforced concrete special-shaped column structure is difficult to meet the bearing capacity requirements due to the limitation of the length and thickness ratio of the column section, the crowded reinforcement in the node area, and the unsatisfactory seismic performance and difficult to deal with. The advantages of the special-shaped column cannot be fully reflected, thereby limiting its application range and maki...

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 type T-shaped section special-shaped steel column is selected, the web shear strength will be much more abundant. However, in order to ensure the local stability of the web, it is necessary to meet the 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 T-shaped cross-section special-shaped steel columns, in addition to their limited shear bearing capacity, seismic performance and overall stability, the truss-type webs 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
