Research on Trial-design of Reactive Powder Concrete Footbridge
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.
