I'm designing a sprinkler system that uses 1-1/2" diameter pipes working their way through a roof structure.
Once I got the branches run, it occurred to me that they could be sufficient to provide water to the system on their own. I looped the ends together, ran hydraulic calculations, and that theory checked out.
The issue is - how am I to seismic brace this pipe?
I have the pipe "restrained" as branch lines, but there is no main that they tie into. Even if I had a main, these branch pipes take so many turns that functionally it would act isolated from the bracing on the main.
How best should I approach this situation?
