| Abstract: | A new SMA-rolling isolation bearing and its restoring force model is proposed. The new bearing is installed in the base of the torch tower. The time-history analysis of the seismic responses of the isolation system is performed under El-Centro seismic curve. The results are compared with the non-isolated system. According to the outcomes, the maximum absolute acceleration of the mass layer may decrease by 86.6% due to the SMA- rolling bearing, the overturn force can be cut by 72.9% and the axis force can be reduced by 87.2%. |
