steel building construction is beeing adopted all over the world .
1. The structure of light weight. According to comparison, the same architectural style, six-storey steel structure housing is only equivalent to the weight of four-story brick-concrete structure house. The Building of total mass is small, the small effect of seismic forces, and good ductility, the corresponding seismic excellent performance. Comparative information on previous earthquake disasters have illustrated this point. 2.the line of Materials isotropic mechanics assume that improved design accuracy. 3. As the factory processing and manufacturing, high precision, easy to ensure the quality, and concrete,they are better in line with structural design requirements. At the same time the construction speed, duration shortened by 40% or more, making building earlier to put into use, early productive. 4. In the design due to request of the owners often have to make changes, using steel is easier to cope with change. Construction of dry-type operations to reduce pollution on the environment, and components easy transportation and low cost. 5. Could be holes in the beam web at walking pipeline, unlike the concrete structure by the end of the beam. Therefore, in the same situation as a high floor under the steel structure can improve the clear height between layers. 6. Lightweight high-strength, simple and complex geometric realization of long-span structures, the creation of an open house. The traditional structure (brick, concrete) due to material constraints, the bay is generally 3.0m, 3.3m, 3.6m, 4.2m. If you need more bays, it will result in a "fat beam column", the high of the housing also be affected. In the same circumstances, the steel bay comparable CONCRETE 50%. In the beam-column under the conditions of equal strength, increase the effective using of the construction area of 5% ~ 7%. 8. The wall is generally used for residential structures with matching plate, compared with the traditional brick wall,it has better thermal insulation performance, building energy conservation has a distinct advantage. This shows that the steel structure housing not only accelerate the pace of development of the state and city leding to the associated development of other sectors, but also improve the quality of housing and people's living standard, it is the overall economic efficiency as a commodity high can benefit both buyers and sellers. Steel Residential housing industry has also contributed to the development process, particularly the use of materials, environmental protection, bringing some good to society overall efficiency, compared to the steel mixing brick and other traditional structures ,they are increasingly exposed them to domestic shortcomings, and obstacles to development, taking the belt of the steel structure has reached the stage imperativly, which is the current stage of development of residential steel causes
