I checked out a small drywall job the other day and noticed the 2nd floor was sagging. Basically its a diningroom that cantilevers approx 8' past a solid wood beam. The room is about 10' wide and 16' long. The joists are perpendicular to
the wood beam.
The drop at the end of the joists is about 2". The joists are 2" x 10" @ 16" o.c. At the point where the joists are supported by the wood beam, the floor has a hump. The house is about 30 years old, the current owner has been in it less then 2 years.
A couple of framing books I have state that cantilever joists, when they are carrying load bearing walls (in this case an exterior wall and roof) cannot cantilever out more than the depth of the joists.
Does anybody know if this is the case or is it more complicated than that.
thanks for any input,
Bruce
