I am building a deck where the joists come from a ledger on the wall and then sit on top of several beams. I was planning on using huricane hangers at all the points where the joist crosses the beams. I was just wondering since I am going to be putting deck planks on this structure how necessary are those hangers? seems like the deck planks would suppy all the reinforcement needed?

You need something to fasten the joists to the beam. Hurricane straps are a viable choice. Check with your building department, but in my town there's a minimum load capacity requirement if you use hurricane straps for this application.

As GBR noted, the 2006 IRC code for decks shows three acceptable techniques for attaching a joist to a beam, Figure 6. This code may not apply in your area, check with your building inspector. If it does apply, as GBR noted, toenailing is acceptable only if the deck is attached to the house. Option two is a hurricane clip. Option three is a joist hanger, which only applies if the joist top is flush with the beam, apparently not the case here.

Toe nail the joists to the beam(s) and then throw a hurricane tie on each joist. They're "probably" overkill but I used them on my deck so what the hey! They're dirt cheap and cheap insurance. Cheers!

Why attach the joist to the beam? Suppose you did not attach any of the joists to any of the beams. Then in the event of uplift (read high wind), or earthquake, the joists would simply walk off or fly off the beams, taking the deck with it. Much as a roof is required to be attached to the perimeter walls using hurricane clips in hurricane country.

The beam acts as a lever hence the term cantilever. I just don't see the need to give more money to Simpson two screws or nails are suffice.

When I did my deck, I used Simpson Hurricane clips to anchor the joists to the beams.
The inspector liked it so well, that he gave me the GREEN sticker and left. Never bothered to look around any further.
When he was walking away, he turned and said I wish all my jobs were like this! :yes:

Even though it usually is overkill, you gotta do what you gotta do.
You can't be a professional if you don't act like a professional!! :thumbsup:
