Removing End Bays in an Old PEMB
Removing End Bays in an Old PEMB
(OP)
As the title implies, I have an old PEMB that has experienced significant settlement in the last 2 bays due to expansive soils. The owner doesn't have the money to rebuild and I've considered suggesting he demo the last 2 bays and creating a new end wall on the remaining building. Does anyone see any issues with this if the lateral x-bracing is not in the last 2 bays? The building is not very tall. I would construct a new grade beam and have studs span the end wall from slab to end frame (previous interior frame).

In fact, the new end wall should be twice the lateral capacity needed...

Also, you're now going to have edge (zone 2 and 3 for the roof, Zone 5 for the wall) wind loads. If the building even complied with its design wind loads, the new ones are likely higher and applied in different ways.
This is not a slam dunk engineering undertaking. You're taking full ownership and liability for this building design. Don't underestimate the surprises and difficulty of it. You might have to measure the frames, purlins and girts to the gage thickness level. These building are designed to the gnat's butt if you're lucky.
