Concrete Bridge Deck Design with Floor Beams

[mrg2771]

I'm looking for a concrete bridge deck design example with transverse floor beams. I'm designing a replacement concrete bridge deck for a 60' span through girder bridge with floor beams on 6' spacings. The deck is approximately 30'x60'. Further, to complicate matters I have no drawings of existing deck and the project is on a fast track. Any help would be appreciated.

Thanks,

Have checked the Xanthakos book on bridges and has something but not a complete example to follow. Other manual over 1000 pages don't even list the (old) type.

I also have an spanish article of the thirties' on the Viaducto de Teruel, where the bridge had (has) both transversal and longitudinal RC beams, but the transverse formed parts of frames resting on parabolic arch. So no same type and I think no calculations, either.

In your predicament I would model the bridge in FEM and look what the Xanthakos and AASHTO standard (or applicable) says. It is a matter of loading mainly for everything else the analysis programs may provide.

Design it as a continuous concrete beam, 1-foot wide.
