Extended data:

The application of steel structure system in residential buildings can give full play to its good ductility, strong plastic deformation ability and excellent earthquake and wind resistance, and greatly improve the safety and reliability of residential buildings. Especially in the case of earthquake and typhoon disasters, steel structures can avoid the collapse of buildings.

Compared with ordinary reinforced concrete structure, steel structure has the advantages of good homogeneity, high strength, fast construction speed, good seismic performance and high recovery rate. The strength and elastic modulus of steel are many times higher than those of masonry and concrete.

Therefore, under the same load, the weight of steel members is lighter. From the aspect of being destroyed, the steel structure shows signs of large deformation in advance, which belongs to ductile failure structure and can find the danger in advance and avoid it.
