Steel structure is an engineering structure which is made of steel and steel plate by welding, bolt connection or riveting. Reinforced concrete structure is an engineering structure which is composed of steel and concrete. The main difference between steel structure and reinforced concrete structure is that steel structure is connected by steel, while reinforced concrete is composed of steel and cement sand, It has obvious disadvantages such as heavy weight, poor crack resistance, poor heat insulation and sound insulation
At present, the application of steel structure is expanding. Compared with reinforced concrete structure, steel structure has obvious advantages of energy saving and environmental protection, high strength, good seismic resistance, fast construction speed and suitable for factory production.
