Why is the seismic performance of steel structures good?

The steel structure has good ductility and can offset the energy consumption of seismic waves. Steel is basically an isotropic material with high tensile, compressive, shear strength and good ductility. Especially the steel structure, due to its unique high ductility, reduces the seismic response. Steel structure can also be regarded as an ideal elastoplastic structure, which can absorb and consume seismic input energy through the plastic deformation of the structure, thus having a high seismic capacity. Compared with other structures, steel structures are lighter in weight and greatly reduce the impact of earthquakes. Steel structure not only has high seismic performance, but also has short construction period, high degree of industrialization and good environmental protection performance, which is obviously better than concrete structure. Thus, the total solution is 4 points:

1. Under the same scale, the weight of the steel structure is lighter, and the seismic energy received at the time of the earthquake is less;

2. The steel structure has good ductility, and the instantaneous deformation of each member is easy to coordinate with itself;

3. The steel bar material is isotropic, homogeneous and flexible, and can withstand the repeated action of earthquakes without brittle failure; the instability has a significant period of time, which is conducive to escape;

4. Steel has strong plastic deformation and consumes a lot of energy. When plastic deformation occurs, steel still has good shock resistance.

The earthquake resistance of the house is also related to the design of the house. Generally speaking, the seismic performance of bungalows is better because the floors of bungalows are lower and more stable. Those buildings with high floors, more complex apartment types, and more beautiful appearance of buildings should greatly improve the seismic standards of such buildings! No matter what kind of houses, they must be constructed in accordance with strict standards to meet seismic requirements. The country now recommends building houses with steel structure materials, which will improve the seismic performance of houses! Fabricated steel structure
