However, earthquakes cause serious damage to various building structures, particularly prefabricated houses. The seismic isolation technology is a technology which is developed rapidly and is improved continuously in the seismic field in the last thirty years, and is mainly applied to the field of building structures at present.
When the seismic level is large and the expected seismic requirement is difficult to meet, the seismic isolation technology is adopted to reduce the input seismic energy, and a good effect can be achieved. The essential role of seismic isolation is to separate structures or components from seismic ground motion or support motion that may cause damage, reducing the seismic force and energy input to the building structure, thereby reducing the seismic response of the superstructure to meet the desired fortification requirements.
The existing fabricated house anti-seismic structure is often complex in structure, and an anti-seismic device is generally only used for simply cutting off the propagation path of seismic energy, so that seismic force cannot be effectively dispersed and consumed, and the house structure is seriously damaged.
