The application of steel structure in residential buildings.

Steel structure is a structure made of steel as a material to be force-bearing members. Steel structure residences have comprehensive advantages such as light weight and low foundation cost, suitable for weak foundations, easy installation, fast construction, short cycle, quick return on investment, less pollution to the environment, and good seismic performance, which are valued by all parties.

Compared with other structures-brick-concrete structure and concrete structure, steel structure has advantages in use function, design, construction, and comprehensive economy. The advantages of applying steel structure in residential buildings are mainly reflected in the following aspects:

1. The functional areas can be arranged reasonably.

Taking advantage of the high strength of steel, the design can be arranged with large bays, so that the building plane can be reasonably separated, flexible and convenient, and create an open house. The traditional structure (brick-concrete structure, concrete structure) restricts the freedom of space layout due to the nature of the material. In the past, the openings were usually 3.2 meters, 3.4 meters, and 3.6 meters. If they are too large, the plate thickness, beam height, and column will be large. , Not only affects the beauty, but also increases the weight and cost. Buyers often change the position of the wall by themselves during the secondary decoration, which increases hidden dangers.
 
2. Light weight and good seismic performance.

Building floors with the same building area have a light steel structure. According to comparison, the weight of a six-story light steel structure residence is only equivalent to the weight of a four-story brick-concrete structure residence. Moreover, steel is ductile and can better consume the energy brought by earthquakes, so it has good seismic performance and high structural safety.
 
3. Convenient construction and short construction period.

Steel structural components can be manufactured in factories and installed on site. Due to the small amount of on-site work and less pollution to the surrounding environment, at the same time, the high degree of construction mechanization speeds up the construction speed. According to statistics, for buildings of the same area, the construction period of steel structures can be shortened by one-third compared with concrete structures, and formwork materials can be saved.
 
Fourth, the comprehensive cost is low.

Due to its light weight, lower basic costs, lower overall materials, lower direct costs, shorter construction period, and reduced indirect costs, the overall cost is low.
 
5. Meet the requirements of residential industrialization and sustainable development

The steel structure is suitable for mass production in factories, with a high degree of industrialization, and can integrate advanced products such as energy saving, waterproofing, heat insulation, doors and windows, and complete sets of applications to integrate design, production, and construction to improve the level of residential industrialization.
 
In general, steel structure is suitable for innovative residential structural systems. The steel structure can be designed with various shapes, sizes and spaces in accordance with people's different aesthetics and different functional requirements.
