Steel structure plays a vital role in modern architecture because of its light weight, high reliability and good seismic performance. Steel not only has excellent shock and impact resistance, its industrial production is also very high, so that components can be quickly and accurately assembled. It should be noted that the steel structure also has the shortcomings of easy corrosion and poor fire resistance, which requires corresponding protective measures to be taken in the design and construction process.
The steel used in steel structure mainly includes carbon structural steel, low alloy high strength structural steel, high quality carbon structural steel and alloy structural steel. These materials are widely used in different structures and components according to their properties, such as high-rise buildings, long-span structures, and various specialized structures.
When selecting steel structure materials, it is necessary to ensure the bearing capacity of the load-bearing structure and prevent brittle failure under certain conditions. In addition, the importance of the structure, load characteristics, structural form, stress state and other factors should be considered comprehensively to ensure that the selected material meets the requirements of the steel structure design code.
