Reactive　powder　concrete　(RPC)　is　a　kind　of　cement-based　composite　material　with　super-high　compressive　strength,　high　toughness　and　good　durability,　which　could　be　used　for　footbridge　and　make　the　bridge　economic,　aesthetic　and　durable.　Taking　a　steel　footbridge　with　a　main　span　of　47m　as　prototype,　a　trial　design　of　RPC　footbridge　is　conducted.　Analysis　results　show　that　the　RPC　footbridge　has　a　higher　performance-price　ratio;　its　girder　materials　only　cost　61%　of　that　in　the　original　bridge.　Compared　with　the　PC　footbridge,　RPC　bridge　has　higher　structural　behaviors,　its　concrete　and　external　tendons　decrease　56.4%　and　18.2%　respectively,　which　results　to　a　reduction　of　53.9%　of　the　self-weight.　Therefore,　RPC　footbridge　has　considerable　application　advantages　and　is　feasible　for　practice.　©　the　authors.
