Anti　-collision　devices　can　reduce　the　damage　of　bridge　columns　under　ship　collision,　and　a　new　type　of　device　is　proposed　in　the　paper　using　a　combination　of　titanium　steel　and　recycled　tires.　The　use　of　titanium　steel　is　to　improve　the　corrosion　resistance,　and　the　use　of　recycled　tires　is　to　improve　self　-floating　capacity　as　well　as　save　the　cost.　Three　test　specimens　were　designed　and　tested　to　investigate　the　behavior　of　the　device　under　impact　load　and　reveal　the　failure　mechanism;　finite　element　models　were　conducted　to　analyze　and　compare　with　the　experimental　results.　Also,　parametric　study　was　conducted　to　reveal　the　effect　of　parameters　on　the　ultimate　capacity　of　the　device.　The　performances　of　different　types　of　the　anti　-collision　device　are　compared,　and　the　failure　mechanism　is　studied.　The　results　show　that　the　proposed　device　effectively　improves　the　performance　of　buffering　energy　dissipation　and　durability　under　impact　load.
