My client wants to cantilever the second story 2 to 4ft over the
first story at the front and back. I propose supporting it on cantilevered
WF beams at 10 or 12’ oc. spanning from the center beam to the o/s walls. The beams support no load other than the roof and wall load of the 2nd story.
The floor joist do not cantilever but span from o/s walls to the center beam.
I wonder how to calculate the upward deflection of the cantilevered Wf’s at mid span and even it is significant.
