| Abstract: | Based on the super-elastic behavior of the shape memory alloy,a new type of SMA sliding bearing is developed by compositing shape memory alloy(SMA) wires with the sliding bearing,and is used in one base-isolated structure.In this paper,a motion equation of this is deduced under the ground motion.A numerical simulation analysis about the seismic isolation is investigated.The results show that the new SMA sliding bearing has nice seismic isolation performances,and is very effective in vibration control of the... |
