Thread: Cantilever and Tributary Area

Situation, Canadian code requires that

cantilevered floor joist extend 6 times the length of the cantilever to a double header joist when loaded by a roof.

The loading in this case when it is most severe is when the truss run in the same direction as the joist i.e. to ward the front of the home..

I think this distance could be less if say the cantilever was supporting only a gable end and not all the trusses. Tributary area is significantly less in the second case and therefore so is the load.

Any thoughts?
