Steel structure widely applies for house construction, basic facilities building and so on. It is important because its good features such as durability, resistance of corrosion, resistance of acid, good strength and excellent tensibility and stretchability. Now we need to know about steel structure concept and related knowledge.
Concept of steel structure
Steel structure is a structure composed of steel materials, which is one of the main types of building structures. The structure is mainly composed of beam steel, steel column, steel truss and other components made of section steel and steel plate. Silanization, pure manganese phosphating, washing and drying, galvanizing and other anti-rust technologies are adopted. Welds, bolts or rivets are usually used to connect components or components. Steel Pipe Because of its light weight and simple construction, it is widely used in large-scale factory buildings, venues, super high-rise and other fields.
Advantages about steel and steel structure
Steel is characterized by high strength, light weight, good overall stiffness and strong deformation capacity, so it is particularly suitable for building large-span, super-high and super-heavy buildings; good homogeneity (uniformity) and isotropy of materials, which belong to ideal elastomer, most in line with the basic assumptions of general engineering mechanics; good plasticity and toughness of materials, which can have large deformation and can well withstand dynamic loads; It has a high degree of industrialization and can carry out specialized production with a high degree of mechanization.
High strength steel should be studied in steel structure to greatly improve its yield point strength. In addition, new types of steel such as H-shaped steel, T-shaped steel and profiled steel sheets, should be rolled to meet the needs of large-span structures and super high-rise buildings.
