OSB Shear Wall Blocking
OSB Shear Wall Blocking
(OP)
I am requiring a contractor to go back and add blocking to about 8280 s.f. of shear walls.
1. Can a 2x4 placed flatwise be used for blocking the panel edges? The 2x8 studs are placed at 8" and 16" centers.
2. If some blocking is present behind one panel edge and the adjacent panel edge is not blocked, could another block be nailed to the 1st block and also nailed to the other panel edge?

The answer to 2 is yes.

Remember that flat blocking is allowed in a roof diaphragm, so it is OK here as long as the penetration is covered.

why use staples? we prefer nails or screws

We got involved in the project after the walls were erected. They used staples. We checked the diaphragm with staples and it passed.
