lateral for decks
(OP)
What are you folks using for lateral bracing for raised wood decks attatched to the house (via ledger board and joists) on one side, and supported by columns on the opposite side. I suppose I could design a steel column w/ moment connections, but I'm not really seeing that in conventional light weight wood constructed homes. Or, are some assuming All lateral reaction can be transfered to the ledger. Any thought are appreciated. thanks.........






RE: lateral for decks
1. Use columns as cantilever posts
2. Knee brace columns to provide stiffness.
The side attached to the ledger board should go into house foundation through the sheathing.
I think the load for a deck would be fairly low (no area due to no walls). However, I have not had the opportunity to investigate this situation and wonder about some of the things I see on houses and apartment buildings in my area.

The bottom line, the forces are transfered to the ledger board, and you can use Simpson straps connecting the end joists back to the main floor structure for your chord forces.

It would seem that there may be some benefit from a fully "blocked" deck diaphram, I'm thinking greater diaphram rigidity
(although I don't plan to detail it this way because the cost vs benefit does not merrit).
any final thoughts??
