To　study　the　control　efficiency　of　a　shape　memory　alloy(SMA)　pseudo-rubber　metal　(PRM)　damper　on　a　seismic　pounding　of　a　high-pier　bridge,　based　on　El　Centro,　Taft,　and　artificial　ground　motions,　seismic　pounding　shaking　testing　and　seismic　pounding　shaking　table　testing　of　a　high-pier　bridge　steel　model　are　carried　out.　The　control　efficiency　of　an　SMA　PRM　damper　is　analyzed　in　detail.　Results　show　that　SMA　PRM　possesses　favorable　damping　behavior,　and　its　stiffness　becomes　large　with　increasing　distortion.　It　can　effectively　mitigate　the　seismic　pounding　in　high-pier　bridges,　and　play　a　role　in　resisting　drift　between　the　main　and　the　approach　bridges.　An　SMA　PRM　damper　is　adapted　to　reduce　seismic　pounding　devices　and　restrictor　in　high-pier　and　long　span　bridges.
