Cantilevering Wood Balcony, Anchored to Masonry
Cantilevering Wood Balcony, Anchored to Masonry
(OP)
So I want to design a cantilevering deck, 25 feet off the ground for an apartment. The deck will extend 5.5 feet from a double-wythe masonry wall, and will be 7.5 feet in width.
I don't want to extend the interior floorjoists for this application due to deterioration/leakage concerns. I want to have a system relying on anchor bolts to ledgers.

The above link is what I was thinking of doing, with anchorages/through bolts going through the two wythes of masonry. My question is:
The horizontal force applied to the masonry wall from the diagonal support pushing the bottom ledger...what code ruling should I follow for concentrated horizontal load (per foot of wall of course)? Any other thoughts on design welcome as well.
Thank you.

However, I wanted to see if this scheme (without vertical support from one adjacent side) would work if I just considered anchoring into one wall, with diagonal supports imparting both horizontal and vertical force further below on the wall.

Good luck, I doubt that it will work as shown.

This one may make me toss and turn a little at night.

We had a local situation about one week ago where a second floor balcony collapsed under the weight of seven people during a small party. It turned out there was wood rot (the newsreel showed mushrooms growing out of the beams lying on the ground). Fortunately, no one was killed, but there were some serious injuries.
Your situation is a little different, it is true, but you cannot take a chance on such a flimsy structure.
