Shape　Memory　Alloy　(SMA)　is　a　type　of　material　that　offers　some　unique　characteristics　for　use　in　devices　for　vibration　control　applications.　Based　on　SMA＇s　material　properties,　four　types　of　control　devices　that　incorporate　NiTi　SMA　wires　are　introduced　in　this　paper,　which　include　three　types　of　dampers　(SMA　damper,　SMA-MR　damper　and　SMA-friction　damper)　and　one　kind　of　isolation　bearing　(SMA-rubber　bearing).　Mechanical　models　of　these　devices　and　their　experimental　verifications　are　presented.　To　investigate　the　control　performance　of　these　devices,　the　SMA-MR　damper　and　SMA-rubber　bearing　are　applied　to　structures.　The　results　show　that　the　control　devices　could　be　effective　in　reducing　the　seismic　response　of　structures.
