Background
Earthquake is also called earthquake and earth vibration, and is a natural phenomenon that earthquake waves are generated during the vibration caused in the process of quickly releasing energy from the earth crust. The mutual extrusion and collision between the plates on the earth cause the dislocation and the fracture of the plate edges and the plate interiors, which is the main reason of the earthquake. The earthquake is extremely destructive and dangerous to buildings, so that life and property losses are caused, and even urban function paralysis is caused, therefore, common buildings all require corresponding earthquake fortification requirements for heavy projects and lifeline projects.
