Steel is a kind of steel that we commonly use now. Because of its high strength, light weight, good overall stiffness and strong deformation ability, it is long used to build large-span, super-high and super heavy buildings. Moreover, its material properties are most in line with the basic assumptions of general engineering mechanics. The material has strong plasticity, good toughness and large deformation, It can bear the dynamic load well, the construction period is short, and its industrialization degree is high, and it can carry on the specialized production with high mechanization degree.
The steel structure is composed of steel materials, which is one of the main types of building structure. Its structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates. The components and parts are usually connected by welds, bolts or rivets. Because of its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields.
