Longitudinal Stiffeners & Block Shear in Coped Beams
Longitudinal Stiffeners & Block Shear in Coped Beams
(OP)
Another structural engineer and myself are having a problem with block shear at the ends of coped stringers on a straight, steel bridge. The ends of most of the stringers must be coped around the flanges of the floorbeams, so block shear is an issue. In order to resolve this, we've thought about adding longitudinal stiffeners (see AISC SCM 14th Edition, page 9-18).
My question is: when adding these stiffeners, does this preclude block shear as a failure mechanism? We've both thought through the physics and have our own ideas, and I was hoping to see what most people thought on this topic.
Thanks!

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.
