Short Span Modular Composite Bridges
A modular concept is presented for short span composite bridges that is based on simple to place prefabricated steel modules. No steel work is required on site. It allows multi-span multi lane elevated roads. Various concrete deck types can be used, from prefabricated over hybrid to cast-in-place solutions. Reinforcing and formwork is greatly simplified by the absence of concrete cross-beams. Hogging moments can be adjusted by the choice of reinforcement allowing for an easy optimization of the moment distribution. The simple moment connections are very efficient but need further investigations with respect to fatigue. A gap between cross beams of adjacent modules requires a gasket which principle is well established but needs detailed design. Because it greatly simplifies the concrete work and moves all steel work into the shop, this concept is superior in economy over other solutions and competitive to pre-stressed concrete for short-span and elevated road bridges.
