Definition and classification of steel structure

18 Aug,2023

The steel structure is mainly composed of steel plates, section steel, steel pipes, steel cables and other steel materials, which are connected by welds, bolts or rivets. Compared with other structural forms such as reinforced concrete structures, masonry and other masonry structures, steel structures not only have many advantages such as high strength, light weight, good plastic toughness and seismic performance, but also are suitable for mechanized processing, with a high degree of industrialization and a short construction period. short. Since materials such as cement and sand are rarely used, environmental pollution problems such as dust, construction waste and noise have been greatly reduced, which meets the requirements of sustainable development.

As one of the most important forms of building structures, steel structures are widely used in housing construction, machinery, energy, municipal facilities and other industries. There is no uniform standard for the classification of steel structures. According to the application field, it can be divided into equipment steel structures (sealed pressure vessel steel structures, tower mast steel structures, ship marine steel structures, water conservancy steel structures, coal and electric power steel structures, drilling tools and brazing steel , underground steel structure, etc.), architectural heavy steel structure (high-rise steel structure, heavy factory building, etc.), architectural light steel structure (light factory building, steel structure residence, etc.), bridge steel structure, space steel structure and other five categories
