I've got an interior load-bearing wall that will have TJI joists bearing on it from both sides. One side has 9 1/2" deep joists, the other has 16" deep joists, and the tops must be at the same elevation. How should this be detailed? Would the 9 1/2" joists have blocking beneath them to get their...
I have an RFI from a contractor saying he can't get a 16' C10x30 beam into place without cutting it in half and splicing it together. For various reasons, I don't believe welding is an option where this beam is, and the contractor wants to splice the beams with bolts and a single plate. A good...

Boss 1 says that for pedestal reinforcement, as long your longitudinal (vertical) bars are 6" or...
I've run into this problem before. I'm trying to model a W6x20 in plate. I modeled the flange using one large plate. I then tried to submesh it using the quad submesh tool. I want 1/2" square elements, so I told it to submesh using 12 elements along the 6" wide flange (okay, I actually did it as...
