I do a lot of 2nd and 3rd story decks and I wonder if anyone has an alternative to joist hangers.Some suggested “pressure blocking”(a block between the joists) but is this acceptable.It seems to me the shear is the same.Also I usually have no room for a ledger.Any help would be good.Andrew

Free standing decks is an alternative to a ledger board, but I would not advocate a free standing deck 3 stories up. Yikes!
Here in SoCal, joist hangers are the only alternative, and one can not use any form of wooden blocking as an alternative. They are simply stronger than a 2x4.
I guess I don't understand why you think you don't have room for a ledger. Jeez, assuming one nails a ledger over studs, it only adds 1 1/2 inches. Must be a pretty short deck, huh?
*Maybe he's talking about a '' ledger" under the joists , maybe interfering with windows or doors below. I'd stick with the hangers and paint them if it really bothered me . I dont like the idea of sand wiching two peices of wood together when it can be avoided .Just one more place to trap water . Chuck
