The man component of steel structure is steel, and the structure of steel structure building system is relatively unified. When the stress of steel structure is consistent with the test results of engineering mechanical design, the calculation theory of steel structure will be effectively applied and improved. The steel structure has the characteristics of simple manufacture, short construction period and strong air tightness. It is suitable for structures with strict requirements on air tightness and water tightness.At present, the corrosion resistance, heat resistance and fire resistance of steel structure are poor, which has been effectively improved. The application scope of steel has also been expanded. The main component of steel structure design is the connection of members. The key is to use mechanics to scientifically deal with the relationship between arm strength and moment of each component, and connect each node reasonably and effectively.
