Joists are unstable until braced laterally.
Bracing Includes:

Blocking
Hangers
Rim Board
Sheathing
Rim Joist
Strut Lines

1. 1x4 (min.) safety bracing must be nailed to each joist and nailed to a braced end wall or sheathed area.  Without this bracing, rollover can occur from light construction loads or a worker.
2. All blocking, hangers, and rim must be completely installed and properly nailed.
3. A braced end wall or an existing deck must be established at the ends of the bay.
4. Sheathing must be completely attached to each TJI(R) joist before loading.
5. End of cantilevers require safety bracing on both the top and bottom flanges.
6. Flanges must remain straight within 1/2" from true alignment.
