H-shaped corrugated web steel column

Abstract

The invention discloses an H-shaped corrugated web steel column. The H-shaped corrugated web steel column comprises a corrugated steel web and two plain plate flanges, wherein the corrugated steel web is arranged between the two plain plate flanges; the connection points of the corrugated steel web and the plain plate flanges are in the middle of the width of the plain plate flanges; the corrugated steel web is curved, folded or trapezoidal. The steel column is reasonable in section composition, has good mechanical properties, high bearing capacity, good ductility, excellent anti-seismic property and simple structure, is convenient and fast to produce and process, saves steel and is low in cost.

Description

technical field [0001] The invention relates to a novel structure in construction engineering, in particular to an H-shaped steel column with a corrugated web. Background technique [0002] Steel structure has become more and more prominent in my country's modernization construction, and has been 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 steel structure, the traditional H-shaped steel column with flat web is usually used. In the multi-story steel structure, the cross-sectional size of the H-shaped steel column is usually very large, especially the web size. In order to ensure the local stability of the web and meet the web height-to-thickness ratio limit specified in the "Code for Design of Steel Structures", either increase the web thickness or add longitudinal stiffeners. No matter which solution is adopted, it will increase the ...

Problems solved by technology

No matter which solution is adopted, it will increase the consumption of steel and increase the construction cost

In addition, the traditional H-shaped steel column with flat web still has a big disadvantage. There is a large difference in the stiffness of the two main axes, and the materials in the two directions cannot be fully utilized at the same time, which consumes relatively more steel; it increases the construction cost; Adding lateral supports or adding longitudinal stiffeners to the web to increase the stiffness of the weak axis will obviously not only increase steel consumption, but also lead to stress concentration at the joints, complicate stress, and increase structural stress. The complexity and difficulty of construction will increase the construction workload, reduce the construction speed, and increase the construction period, thereby increasing the overall cost of the project.
