girders w/sweeps
(OP)
Would the formulae for bending and shear applicable to straigth beams (assume simply supported) apply to simply supported beams w/ sweeps? Are there correction factors?Where could I find such info. for such beams?

If you're not up to going that far back to school, you could possible find coefficients for the problem in either Roark's Stress and Strain or Practical Stress Analysis by Blake.

Thanks for the description. I've always known them as "Horizontally Curved Girders". You're right torsional warping stresses can jump up and bite you.
Thanks, Tincan.

Torsion may be "simply" included in the equation for stress or deflection and will affect any allowable stress equation since the interaction of all (as many components you're including) components are usually compared to unity.
Beyond that above you'll have to investigate what component of torsion is added or subtracted to the shear diagram and similarly with bending. A good stress block diagram is in order.

"Horizontally Curved Girders" Highway Structures Design Handbook Vol 1 by United States Steel is a "how-to".
Both of these are old prints, but worth while if you can find them. Otherwise check out a good textbook on advanced steel structures.
Best, Tincan.
