You're Welcome Sharon.
And for some reason I have no doubt you know the difference between
the first responsibility (heat detection) and the second
responsibility (putting enough water on the floor).

So ... you're suggesting that sprinklers be ... spaced as
detectors? What's the "deflector" distance of a heat detector
and how would that translate to sprinklers on branch piping
exactly? What the hell are you even talking about? I get that
sense Brad that, at this point, you're just posting for the sake of
seeing your words in print because that's the 2nd-most ridiculous
thing (after the Ghost Ship comment) you've ever put up. Please,
just stop.
Sharon - since it's framed of wood, I'd look at the criteria for
depth and on-center the spacing of the members. It's likely to end
up being (or closest) to Wood Joist Construction per A.3.7.1 (6)
and that section even includes criteria on the span. The
honeycomb elements will catch head just as solid wood or composite
joist members will; the honeycomb pockets look (in photos, I had to
Google "Lamella Roof") like the area and volume would be less than
a TJI channel typically is, so heat and combustion byproduct will
log down to the sprinklers pretty quickly. An unusual
configuration by today's standards but I'm not sure it has to be
that complicated for sprinkler locations.

All I've got Sharon is to look at NFPA 72 spacing and position rules
for heat detectors for dome roofs, since the first responsibility of a
sprinkler is to be a heat detector, and 13 does not adress dome roofs.

So, nothing extraordinary? I’m thinking wood joist criteria? I
don’t know yet how deep the wood is, but I’m thinking it is 12” deep.

Years ago in Weslaco, Texas. We called them honeycomb roofs. They
are great and very sturdy and open, good for warehouses. First came
here during and after the great wars via a German engineer.

you; and I will take the stony heart out of their flesh, and will
give them an heart of flesh

I have been asked to provide a design for a gymnasium retrofit.
The gymnasium has a lamella roof system. I have never seen this
before.
I was wondering if anyone in the forum has had experience with a
lamella roof.
