Unsupported partition walls?
Unsupported partition walls?
(OP)
I'm wondering how to deal with unsupported partition wood-frame wall which lie parallel to wood joist floor system direction?
1) Capture its load with every joist in that floor system with additional area dead load on entire floor.
2) Take its whole load on a single joist?
Thank you in advance





RE: Unsupported partition walls?
If the partition wall does not aligy with the joists above, 2X flat blocking can be placed between the joists above at the top of the partition wall to nail the clips DTC to.
The Simpson manual shows how to install the clips. There must be a 1/4" gap between the top plate of the partition wall and the bottom of the joists above. The same detail can be used if the joists above are roof trusses.

Misunderstanding, I mean the wall above the joist (not under).
RE: Unsupported partition walls?
If the partition wall extends 1/2 or more of the joist span, then doubing up on the floor joist directly under the partition wall is all that is needed. Otherwise, a single floor joist is sufficient.

You probably mean doubling?
