Hollow core slab
Hollow core slab
(OP)
I have a situation here where we need to remove and rebuild existing wall supporting (simply supported) 20 feet span, 8" Hollow core roof slab. I need to see if we shore the PC slab 4 feet away from wall, it will work and not crack etc. Also is there any way I can model it is STAAD.

That method doesnt work as the post tensioning will be working against you and increasing the cantilever moment.
dgkhan,
If they can reduce it down to a 2' cantilever and there is no loading on the end then I wouldnt expect it to be a problem. At 4' I would want more info on the planks.
