Curved Bridge Deck
Curved Bridge Deck
(OP)
For the purpose of preliminary design, is there any simple equation which can be used to work out the torsional moment of a curved bridge deck (in plan) if both ends are torsionally restrained.
What I know is that the BM on the bridge is approx equal to w x (arc length)^2 /8.
Another equation I know is dT/ds = - (M/r + ...-->minor terms)

RE: Curved Bridge Deck
this is not big factor. The torsion will be taken out by the full width slab cross section.
