Steel structure engineering steel structure building steel requirements? Steel structure buildings will suffer from various forms of interaction, so the applied steel has excellent mechanical equipment performance and production and processing performance. Xiaobian will tell you how much the steel structure buildings have regulations on the application of steel.

1. Ductility. To put it bluntly, plastic deformation refers to the obvious plastic deformation without fracture after the in-situ stress exceeds the yield limit. The ductility of steel determines its deformation ability.

2. Compressive strength. The compressive strength index value of steel is composed of ductility limit, strength limit and compressive strength limit. Generally, it is based on the yield strength of steel. High yield strength can alleviate the weight of the structure, save steel and reduce the project cost. The compressive strength refers to the in-situ stress that the steel can bear before it is destroyed, which can be used as the main parameter of steel compressive strength reserve.

3. Durability. There are many factors that endanger the durability of steel, and corrosion resistance and heat resistance are the two most important factors. If the steel is corroded or becomes hard and brittle under long-term high temperature, it will endanger its safety performance. Generally, in order to better improve the durability of steel, a series of protective measures must be taken, such as hot-dip galvanized steel and timely maintenance of steel paint.

4. Electric welding performance. In addition to the excellent welding performance and ductility of the welding material in the welding area under the standard of electric welding, it means that the welding material in the welding area can not have the excellent impact and ductility of the original welding material.

5. Impact toughness. It refers to the ability of steel to digest and absorb the mechanical energy of mechanical equipment in the whole process of fracture under the effect of impact load. The effect of steel resisting impact load can be considered. Generally, the impact toughness index value of steel can be obtained through the impact test of standardized samples.

6. Cold drawing performance. It is to consider the resistance of steel to cracks caused by plastic deformation caused by bending production and processing at room temperature, and can detect the bending deformation performance of steel bearing the required bending level according to the cold drawing test.

The application of steel in steel structure buildings may be very high, so as to ensure the overall safety factor of engineering buildings.
