For years we have gone under the assumption when temporarily supporting beams at a distance less than d/2, if welded bearing stiffeners existed between load and end of beam, that d/2 or near end of beam did not apply. We have recently been asked to supply backup for our assumption. Can anyone...
Designing a pinned connection. Want to use HS bolt for pin. A325 assume ductile therefore plastic design is coming out better than A490 assume brittle therefore use elastic design. Is this thinking correct? Thoughts on the matter would be appreciated.

I need to temporarily support bridge beams at abutment. Length from footing varies from 3'+- to 8'+-, want to use segmental HS12x12x3/8 with a single 1x18x18 plate between segments. No more than 4 segments per column. Neoprene will be used top and bottom for rotation at longer columns and shear...
