In this paper, we develop two springs using pseudoelastic SMA wire under vending deformation. One of them is called Ring-Type-Spring, and the other is called Buckling-Type-Spring. We also develop a base isolation device using these SMA springs. The response of the base isolation device with each SMA spring is investigated by experiment and equivalent linearization approach and it is clear that every spring has some damping effect. Especially, Buckling-Type-Spring restricts the transmissibility because of its characteristic of restoring force.
