SMA-rubber　bearing　is　a　new　type　of　seismic　isolation　device,　which　is　composed　of　the　laminated　rubber　pad　and　shape　memory　alloy　(SMA)　wires.　The　present　paper　outlines　the　working　mechanism　of　such　a　new　isolation　device.　Based　on　the　pseudo-dynamic　tests,　the　vertical　stiffness,　horizontal　stiffness,　energy　dissipation　and　equivalent　damping　of　the　new　isolator　are　studied.　In　addition,　the　effects　of　loading　frequency,　vertical　pressure　and　amplitude　of　displacement　on　the　mechanical　behaviors　of　the　new　seismic　isolation　device　are　investigated　in　detail.　The　experimental　results　show　that　the　SMA-rubber　bearing　has　stable　working　property　and　excellent　energy　dissipation　performance.
