Compared with other structures, steel structure has advantages in use, design, construction, and comprehensive economy. Low cost and can be moved at any time. Compared with ordinary reinforced concrete structure, steel structure has the advantages of uniformity, high strength, fast construction speed, good earthquake resistance, and high recovery rate. The strength and elastic modulus of steel is many times higher than that of masonry and concrete, so under the same conditions, the weight of steel components is lighter. From the point of view of damage, the steel structure is a sign of large deformation in advance, and it is a damaged structure that is easy to extend, which can be found in advance to avoid danger.
1. Steel structure houses can better meet the flexible separation requirements of large spaces in buildings than traditional buildings. By reducing the cross-sectional area of the columns and using lightweight wall panels, the area utilization rate can be improved, and the effective indoor area is increased by about 6%.
2. Secondly, the energy-saving effect is good. The wall adopts light energy-saving standardized C-shaped steel, square steel, and sandwich panel, which has good heat insulation performance and good seismic performance. Energy-saving 50%
3. The steel structure system used in residential buildings can give full play to the ductility, plastic deformation, earthquake resistance, and wind resistance of the steel structure, which greatly improves the safety and reliability of the residence. Especially in the event of an earthquake and typhoon, the steel structure can prevent the building from collapsing.
4. The total weight of the building is light, and the weight of the steel structure residential system is light, about half the weight of the concrete structure, which can greatly reduce the basic cost.
5. The construction speed is fast, and the construction period is at least one third shorter than the traditional residential system. A 1,000-square-meter building takes only 2
