Beam camber spliced beam
Beam camber spliced beam
(OP)
I recently detailed a 96' W36x256 with a camber of 1", the erector requested to splice into 32' pieces. I mistakenly left the 1" camber on the the 3 pieces. They have an "M" in the field, they will straighten out the 2 end beams, but they are asking me what the camber needs to be on the center piece, i am not sure if i am figuring it out right. My method is telling me 1/8" but i dont feel i am figuring it out right, any help is greatly appreciated.

Have you checked the beam deflection over a 96' span?

I concur with BA, at just half of what I would expect the capacity of girder this to be it's deflecting 6 inches and very quickly exceeds even the most minimal deflection limitations. Your erector is smart; this thing would have likely folded itself into a pretzel if they tried to lift the full span.
