Steel structure building has a strong seismic advantage. When an earthquake comes, it can become a refuge for life. In the face of new life and property losses caused by earthquake, it is necessary to seriously consider the application of steel buildings in the future. The seismic advantages of steel structure buildings are summarized.

The ductility of steel structure building is good, which can offset the energy consumption of seismic wave. Because the tensile strength, compressive strength and shear strength of steel are very high, it can also be used as an ideal elastic-plastic structure, that is, it can absorb and consume the seismic input energy through the plastic deformation of the structure. In addition, compared with other buildings, the weight of steel structure building is lighter, which also weakens the impact of earthquake, so steel structure building is an ideal seismic building structure.

Steel structure building has good seismic performance, followed by wood structure building, and the traditional concrete structure building seismic performance is not good, but it is still the main building form in our country.

With the development of the times, there are higher technical requirements for the seismic reinforcement of steel structure buildings, and the brand of seismic reinforcement is clear, which is marked with the letter "e". Seismic steel belongs to building steel, which has the advantages of high strength, good toughness and easy welding. It is of great significance to earthquake resistance and disaster prevention, and to reduce the consumption of steel resources.

With the frequent occurrence of natural disasters such as earthquakes, the market demand of steel structure buildings is increasing. The state also attaches importance to the popularization and application of steel structure buildings. It can be said that seismic steel is the inevitable trend of the development of the times. Through comparison, it can be found that most of the buildings in China are brick and tile structures, while Japan, as an earthquake prone country, is mainly steel structure with lighter wall materials, which is safe, earthquake resistant and energy-saving.
