Background

Earthquake is one of the most serious natural disasters threatening human society, and historically causes loss which is difficult to estimate on economy and population, so that reasonably reducing the influence of earthquake on building structure is one of the primary targets of building structure design. In building structure design, seismic energy is often dissipated by adopting an anti-seismic design concept and relying on plastic deformation of structures and members for a long time. The structure of the traditional design can relieve the influence caused by earthquake to a certain extent and reduce the threat of strong earthquake to human life, but the damage of earthquake to the structure is difficult to avoid, and the influence of earthquake on economy and society can not be eradicated. In order to improve the situation, the horizontal shock insulation support is arranged at the bottom of the building structure, so that the self-vibration period of the upper structure is prolonged, the seismic response of the structure is reduced, the upper structure is basically in an elastic state under the condition of large earthquake, and the plastic damage of the structure is reduced, so that the structure is prevented from being damaged too much by the earthquake.

Therefore, the combination of the vibration isolation support and the assembled structure is a research direction with great development potential, and the assembly research of the vibration isolation support system is needed to be carried out.
