Floor Joists Cantilever in MiniHomes Canada
Floor Joists Cantilever in MiniHomes Canada
(OP)
Hello all
I have a question about minihomes, specifically the way the floor joists cantilever over the support beams on either side of the home. We have a group of homes going to northern Labrador where there is a heavy snow load. These are standard minihome designs that are shipped throughout eastern Canada. Would there be a concern or is there an allowance in the code? The NBCC allows for a cantilever of the floor joists (9.23.9.9)does that apply to both ends of the joists?

If it is a standard system designed for no or low snow and it's detailed the way I am saying above for heavy snow, then flexure shear and deflection of those joists should be checked.
Building official would reject a prefabricated element of the mfg's published design loads are less than the local requirements.

Or simply ask the joist supplier they have specs on it.
You will need to rreinforce he joists with plywood over the cant and backspan.
