In some areas with high intensity and near the epicenter, the buildings, especially nuclear power station, lifeline, long-span structures, information and other important buildings, are of obvious vertical earthquake component by the effect of macroseism. So the research on three dimensional shock insulation including vertical earthquake component should be conducted. The horizontal isolation which is widely used for vertical seismic isolation effect is not obvious and its application in practice is limited highly. Considering its defects mentioned, this paper studies the SMA-disc spring three-dimensional composite bearing from the perspectives of mechanical parameters, performance, structure and working principle and applies it to the typical spatial reticulated structure. By comparison, it can get a conclusion that SMA-disc spring three-dimensional composite bearing has better three-dimensional isolation effect.
