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