Does the wall need to be cut above the joists? Can the existing wall hang down to the bottom of the bottom joist chord? this would allow you to sandwich the wall below the joists with some channels, and then cut the wall below the channels. The channels would support the wall, joists, etc.

What about a beam above on the floor inside of the wall, supported each end, then some sort of saddle thru the floor to hang the joists why the wall is removed, a new beam put in place, then your shoring beam reomved. Thats if you have enough room to slide in a shoring beam on the second floor...

What about bearing and stability, i.e. foundations?

Does anyone know what column 14 is for in this table? I understand it that I can increase my stresses for this amount? Does everyone agree?

I thought appendix D took this into account with group factors. I like the idea of DBA's welded on to take the load.

I think that whoever has the majority of the structure should be EOR. I.E, PEMB engineer is EOR and they need to shop out the foundations...I know there are reasons not for this, but it would add some validity to their designs

Yea, I am surprised there are not more of these type posts with all the snow we are having in the midwest/east

I didnt know what a gerber beam was. All they taught us in College was sky hooks and structural paint.

Do you need to leave space for air flow, i.e. not block to the bottom of the sheathing?

Not sure how this was constructed for sure, but a few rebars might have helped. didnt look like there was any if concrete

what is your span? is the slab simply supported?

How are the girders holding up? a 6x6 girder supporting joists sounds fishy. any pictures?

I have seen them done out of Tilt-up, or site cast precast.
