Steel structure has good seismic resistance, light weight, high strength, fast construction, etc., is now the leading building in developed countries, is widely used in high-rise, high-rise buildings. In Australia, Britain, Canada, Japan, the United States, Finland, France, Sweden, Denmark and other countries, have formed a considerable scale of industrial steel structure building system.
Australia to cold-formed thin-walled light steel building system, developed in the 20th century, 60 years, this system is mainly developed by BlueScope's success and the development of relevant business standards. The system is widely used in Australia, the United States, Canada, Japan and other countries for its environmental protection and construction speed, seismic performance and other significant advantages. In Australia, for example, the construction of its steel structure accounted for about 50% of all new homes.
Japan's industrialized housing has three types of wood structure, concrete structure and steel structure. By the end of the 1990s, 18% of wood structures were made of prefabricated houses in Japan, 11% of concrete and 71% of steel structures. Japanese steel structures are mostly built by large enterprise groups such as SEKISUI and PANAHOME. These large companies can bring together almost all of the components of steel construction. More typical is the water company housing branch of the "sea water Mu" (Heim) steel series of residential, all of its processing in the factory production, high precision.
In the United States in the 20th century, 90% of residential steel structure is about 5%, now more than 40%. Multi-storey hotels and apartments in the United States are made up of light steel structures. The multi-story light steel structure building technology is an integrated system integrating light steel structure, building energy conservation, building fire protection, building sound insulation, new materials, architectural design and construction. technology. Finnish steel structure currently has two systems, one is the use of the termo keel light steel keel structure system, the other is the ordinary steel frame system. Termo steel keel structure system to produce hot-dip galvanized thin-walled steel keel, the framework of the insulation performance for the high latitudes of the Nordic countries can greatly reduce energy consumption, other Nordic countries have adopted a similar structure. This system is generally used for detached houses.
Italy BSAIS industrial building system is the new Italian steel company and the University of Genoa to study the design of new housing construction system, the building system modeling, reasonable structure, seismic performance, construction speed, comfortable and convenient office, CAD computer-aided Design and CAM computer-aided manufacturing, in Europe, Africa, the Middle East and other regions to promote a large number of applications.
