Modern light steel structure and its application in my country

Light steel structure is a new type of structure with fast application and development at home and abroad. It is widely used in various industrial, public and residential buildings. It has the advantages of fast construction speed, beautiful building shape, less steel consumption and low cost. This paper reviews and summarizes the development status of light steel structures at home and abroad, and puts forward suggestions for the main problems in analysis, design and application.

In addition, the light steel structure can also replace the brick and wood structure, which can be recycled and in line with the principles of environmental protection and sustainable development. However, as a kind of high-tech content and application of new technology, the quality requirements of designers and constructors are very high, and special training is required. The processing and production needs to establish a professional production line, invest in advance, and prevent structural corrosion. Fire prevention also needs special treatment. Huizhou steel structure.

The commonly used load-bearing systems of light steel structures in China include: Welded portal steel frame structure system, cold-formed thin-wall steel structure system, multi-layer frame structure system, thin-wall folded arch shell roof system. For industrial and civil buildings without cranes, the steel consumption of light steel structures is generally 20 ~ 50kg / m2, which mainly depends on the structural form, span, column spacing and live load.

The application fields of light steel structure in China mainly include: 1. New technology development zone projects, especially high-tech enterprises, mainly adopt light steel structure in order to establish an enterprise image; 2。 Warehousing (grain and cotton warehouse, garage, reserve warehouse), distribution center (industrial and commercial); 3。 Various (small tonnage cranes) light industrial plants; 4。 Shopping center, exhibition hall, gymnasium, waiting room, hangar, studio and other large-span public buildings; 5。 Multi storey residential buildings and multi-storey industrial plants; 6。 School, hospital, office, entertainment and other multi-storey public buildings; 7。 Supermarket, retail, department store and other commercial buildings; 8。 Transformation, expansion, transformation and increase of old buildings.

Light steel structure system and characteristics portal steel frame light house steel structure system adopts portal rigid frame as the main load-bearing structure and profiled steel plate as the enclosure structure. The analysis, design, production and installation technology is mature and widely used. There are many complete systems. The application scope includes various light industrial plants, stadiums, entertainment venues, public buildings, warehouses, storage and transportation facilities, supermarkets, retail and commercial services, and the reasonable span is generally between 18 and 36m.
