The earthquake resistance is to increase the material consumption of the building structure, so that the structure has enough earthquake resistance, and the earthquake resistance method is mainly adopted in China at present to conduct earthquake resistance design on the building structure. The vibration isolation is to set a vibration isolation layer between the top of the building foundation and the upper structure to make the vibration isolation layer absorb the earthquake energy and reduce the earthquake effect transferred to the upper structure. The damping is to set up the energy consumption device in the appropriate position inside the building, let the energy consumption device absorb the earthquake energy, increase the damping ratio of the structure, under the condition that the total earthquake energy is unchanged, reduce the damage that the structure is damaged, adopt the method that combines shock attenuation and shock insulation to carry on the shockproof design of the building structure at present in developed countries such as japan.

In the earthquake, the frame structure is obviously damaged in the beam column node area, and in consideration that the beam columns are structural stress members, once the bearing capacity is lost, irreparable consequences are most likely to be caused. Through the mode that sets up the power consumption device, the power consumption device can assist prefabricated structure dissipation energy, reduces the structure and receives the earthquake influence, guarantees the bearing capacity of component, and compares in the structure atress component, and the power consumption device is because of its vertical load of not bearing, easily changes after damaging.
