1. Seismic advantages: the multi-storey steel structure office building itself light weight, but high bearing capacity, strong seismic performance, has a strong earthquake defense ability, small earthquake damage, easy to restructure after the disaster.
2. The use of steel structure, light steel structure is widely used and has obvious advantages. Can achieve large span, large space segmentation, flexible use, in addition to rapid installation, earthquake resistance to wind highlights, has been widely used in single-storey industrial plants and multi-storey industrial plants, office buildings, as well as non-bearing parts in higher buildings.
3. The steel structure has good sealing performance, and the steel structure is connected by welding, which can be made into atmospheric and high pressure structures and pipes with good water tightness and air tightness. The strength of the material is high, and the weight of the steel structure itself is small. Although the density of the steel material is large, its strength and elastic modulus are high. Under the same stress condition, the cross-sectional area of the steel structure parts is much smaller, and the weight of the structure itself is small.
4. Small dead weight of steel structure, so as to facilitate transportation and installation, can reduce the load of foundation, reduce the cost of foundation and foundation part. Steel plasticity and toughness of good steel plasticity, steel structure in general conditions do not exist due to overload and other sudden fracture, damage generally before most of the significant deformation, easy to be found, can take timely remedial measures to avoid the occurrence of big accidents. The steel structure has good toughness, strong adaptability to dynamic load, good energy absorption capacity and excellent shockproof performance.
5. The corrosion resistance of steel is poor. In the general environment without corrosive medium, ordinary steel is made of steel structure and then coated with qualified coating after shot blasting and rust removal, and the corrosion is not serious. Because the office is mostly in the environment of no corrosive medium, the maintenance cost of the steel structure itself is low.
