Description

Novel H-shaped steel

Technical Field

The utility model relates to a building materials structure field especially involves a novel H shaped steel.

Background

The H-shaped steel is a section form which is widely applied to the vertical surface of a steel structure building, all parts are arranged in a right angle, the area distribution is reasonable, and the H-shaped steel is an economic and efficient section which is named because the section is the same as the English letter H. Because the H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving, light structure weight and the like, the H-shaped steel is widely applied. According to different production modes, the H-shaped steel is further divided into hot-rolled H-shaped steel and welded H-shaped steel.

In structural design, from the perspective of earthquake resistance, plastic hinges may appear at the end parts of the lateral force resisting members (frame beams and frame columns) within a certain range, and in order to improve the energy consumption capacity of the structural members or the developing capacity of the plastic hinges of the structural members, the width-to-thickness ratio of the structural members needs to be reduced; a smaller width to thickness ratio of the structural member is also required from the standpoint of the plasticity of the steel member and the bending moment amplitude modulation design. And in order to ensure the local stability of the H-shaped steel, the specification limits the width-thickness ratio and the height-thickness ratio of the section.

Width-thickness ratio: the ratio of the overhanging width of the flange to the thickness of the flange is 1/2 (W-tw)/tf;

the height-thickness ratio is as follows: the ratio of the effective height of the web to its thickness, H0/tw;

in high-intensity areas, in order to meet the structural requirements, the thickness of the flange and the thickness of the web need to be increased, so that the sectional thickness of the H-shaped steel is not controlled any more, but structural measures such as a high thickness ratio and a width-thickness ratio play a role in controlling, the strength of the steel plate cannot be fully exerted, and the economical efficiency of the steel plate is reduced.

In the design of plasticity and bending moment amplitude modulation of a steel member, the width-thickness ratio of the member is higher, and the traditional H-shaped section plate needs to be thicker in order to meet the design of plasticity and bending moment amplitude modulation, so that the steel consumption is increased, and the method is not economical.

Therefore, it is an urgent need to solve the problem in the prior art to provide a novel H-shaped steel which is convenient for standard production and more economical.
