It is almost certain that it's not a load related bearing failure since it's happening with partial dead load (joists and deck only) and almost no live load. It is a thermal issue and I'm hoping someone has some experience with what that detailing may be. There is precedent in bridge...
The buildings we do are steel beam and joist roof on block bearing walls. So I end up with some 40 to 50 foot span beams at times and even further on the joists. Oddly enough, I've not had the 100' or longer DLH joist do this to bearings.
It's beams and it's roof so they're lightly loaded...
Fellow practitioners of engineering:
A few times now I have encountered masonry bearings fracturing, the face of the wall that is toward the beam span, affecting the face shell of the immediate block or two or three under the beam. It usually a longer span beam during construction. My only...
