Why is it that, at least in Ontario Canada, camber diagrams are required for detailed design drawings (Not shop drawings) for bridges with steel girders, but are not required for CPCI Girders?
My understanding is that the camber drawing is required for the steel manufacture to put in a vertical curved to the beam so that when the dead load of the superstructure is added on top of the girders the whole thing bends to meet the road profile.
For concrete girder this is not done, though a similar process seems to be followed. The screed elevation is adjusted to account for deflection of the concrete, including long term deflection from shrinkage and creep.
I would have thought a screed elevation table would be required for both steel and concrete girder designs, so why have to two different approaches for dealing with deflection to match the road profile?
