From the current architectural form, the use of steel structures in buildings is one of the structures that have the least impact on the urban environment. Among many building structures, when steel structures are used, the steel structure housing system has the advantages of light weight, easy installation, and the like. Here are some of the main features of the steel structure:
(1) Designing steel structure design with large elasticity, high difficulty, large span and special shape;
(2) Due to the reduction of self-weight, the amount of soil borrowed from the foundation construction is small, and the valuable resources of the land are less damaged;
(3) The service life of the building is due, the solid waste generated by structural demolition is small, and the recycling price of scrap steel resources is high.
(4) The calculation structure is accurate, the steel structure is uniform due to the quality of the steel, and the strength of the steel is uniform, which is not as good as other materials;
(5) The tough steel structure can be increased in strength and toughness with improved composition and heat treatment, and the safety is improved.
(6) Reducing the use of concrete and the use of bricks and tiles in a large amount, reducing the excavation of rocks around the city and contributing to environmental protection;
(7) High degree of industrialization and fast construction, which is conducive to the realization of industrial production; non-combustible, non-combustible, and good fire performance;
(8) The light steel structure has a small floor space, which actually increases the use area and increases the use value and economic benefits of the building.
(9) The components of the prefabricated steel structure can be manufactured in the factory, mass production, reduced labor, rapid construction, shortened construction period, easy quality assurance, and higher prefabrication accuracy;
(10) Long-span steel structures have better advantages for beam depth and inter-column span. For example, the beam depth and span ratio of general reinforced concrete is about 1:12, while the steel structure is 1:24.
(11) Beautiful and generous. The supporting materials used, such as color steel plates, aluminum alloys, glass curtain walls and other eras of color change, can be matched with each other to create beautiful and generous buildings.
(12) The weight ratio of steel structure to reinforced concrete is about 1:1.6, and the seismic force = mass 9 earthquake acceleration, so the lighter the weight, the less the seismic force. If the steel structure is properly treated, it is more effective against earthquake resistance;
(13) The steel structure can provide a large space for construction and a relatively spacious construction work surface, and the construction speed is fast. In addition, there are many holes and cavities in the steel structure space, and the webs of the steel beams allow passage through a certain diameter of the pipeline, which also facilitates the arrangement of various pipelines;
(14) As a consensus, the steel structure is compared with the current general use of concrete: First, it can be dry construction, save water, hoisting on site, labor and construction, civilized construction, less land occupation, less noise, Less dust; especially in downtown areas or dense residential areas have great advantages.
