Wood cantilever balcony
Wood cantilever balcony
(OP)
I am designing a backyard timber cantilever balcony that support part of a roof, I understand there has been lots of problem with this type of balcony, I am thinking of extending the floor joist but then water is a big issue. Where can I find information on connection anaysis and design? I am mostly looking for connection details.

I'll admit that I have not seen this done many times, but the few I have seen have all exhibited water infiltration problems and joist rot.

(WF) beam extended out at each end with framing running in between the beams, instead of a bunch of wood floor joists cantilevering out. Just an idea, and it's less holes in the side of your house.

The rule of tumb is for every foot out you need to extend your joists 2 feet in, which will work the same if you use the formulas. You may nail the joists to the existing joists or if the floor support is not too far extend the balcony joists to the floor support system. You may use the pressure treated joists to prevent water problem on the outside and use flashing. Depends on your location and the codes used the cantilevered balconies are supposed to be 60 lbper foot sqaure, IRC 2000. Good luck.
