Compared with concrete, steel frame structure has the following advantages:
1.A large reduction in the use of concrete and bricks and tiles, reducing mountain excavation around the city, is conducive to environmental protection;
2.It can be installed bydry construction, save water, occupy less land for construction, in order to produce less noise and dust;
3.The solid waste generated by the demolition of the structure is smallwhen the service life of the building has expired, and the recycling price of scrap steel resources is high.
4. As the self-weight is reduced, the amount of soil taken for foundation construction is small, and the damage to the precious resource of land is small; the steel structure is uniform, close to an isotropic homogeneous body, with high strength and high elastic modulus. The ratio of density to strength is much smaller than that of masonry, concrete, and wood. Under the same force, the steel structure has a small dead weight, so it can be made into a structure with a larger span and a higher height and a flexible structure.
