Restraint of Branch Lines
Restraint of Branch Lines
(OP)
Regarding NFPA 13 2010, 9.3.6 Restraint of Branch Lines. I have a few questions.
If you are working with branch lines attached at both ends by a main (grid) which is restrained laterally and longitudinally by sway bracing in accordance with the code, do you have to restrain the branch lines within the grid according to 9.3.6?

RE: Restraint of Branch Lines
What size are the branchlines? How long is the run between the mains? How are the branchlines hung, ie, how long is the hanger assembly?

RE: Restraint of Branch Lines
The length of the branch lines between the mains is approximately 200'-0"
The branch lines are hung 21" below the deck with a top beam clamp, 3/8" A.T.R. and a hanger strap.
