The seismic support can dissipate about 80% of the energy of the earthquake through such technology. The seismic support is usually composed of a rubber layer, a steel plate layer and a damping device. During the construction, installation and use of the seismic support, it will be affected by complex external load effects, causing damage accumulation in the internal structure of the support system, weakening the health status and natural disaster resistance of the support.
