Research on the Development of the Three-Dimension Seismic Isolation System for Lightweight Buildings

In the seismic isolation structure, the seismic isolation device is designed to have low horizontal rigidity and high vertical rigidity for obtaining a long horizontal period and stable vertical support capacity. However, due to this, the seismic isolation structure cannot be expected to have a seismic isolation effect in the vertical direction. For protecting human and physical safety from earthquakes, it is necessary to consider the vertical component of the earthquake. In this research, after confirming the mechanical performance of the existing seismic isolation device, a three-dimensional seismic isolation system will be constructed by combining the horizontal seismic isolation device and the vertical seismic isolation device. The purpose is to analyse the seismic response at the building level using the constructed three-dimensional seismic isolation system and propose a three-dimensional seismic isolation system which can provide the better seismic isolation effect.
