The characteristics of steel structurePosted by:W&G International Co., Ltd.
Steel structure is made of steel plate, steel through a connection. Compared with the structure of other materials, steel structure has the following advantages.
(1) high strength steel material, compared with good and concrete, masonry and timber and other building materials, high strength steel, steel from steel production, strict quality control, material uniformity is good, and has good plasticity and toughness. The characteristics of high . The characteristics of high strength steel to make steel suitable for construction of large span, carrying heavy structure. Steel material and good uniformity and the feature of good plasticity of the steel structure, not the overloaded and sudden failure under general conditions, can rely on to adjust the internal forces and deformation increase of redistribution, as the structure reinforcement provides a cushion. The characteristics of the steel toughness is good, so that the steel structure is suitable for working under dynamic load, its good energy dissipation capacity and the ductility of the steel structure has excellent seismic performance, especially suitable for various construction earthquake resistance fortification meizoseismal area. (2) compared with the steel structure of light weight and concrete, masonry and timber and other building materials, although the steel density is bigger, but its strength is much higher, the ratio of mass density and strength of the material for the (1.7-3.7) xlO-4m, and the ratio of reinforced concrete is about 18X10-4m, so the built structure of lighter. In order to thoracic span bearing the same load, the weight of steel roof truss for reinforced concrete roof truss of 1/4-1/3, 1/10 of cold-formed thin-wall steel roof truss and even closer to the reinforced concrete roof truss. The weight of steel structure building is about to the height of the building concrete structure of the 1/2-3/5, and the cross section area of steel structure column is concrete structure column section area is reduced to about half, effectively increase the use of building area. Steel structure of light weight, its installation and transportation provides convenient conditions, while reducing the base load, reducing the foundation, the basal part of the cost.
