Obstructed Construction - Panel Construction

[majesticphil]

Beam and Girder construction with corrugated metal deck forming panels less than 300 sq ft in area....can this be considered panel construction or does the gaps formed above the steel by the corrugated metal deck mean that sprinklers will need to be installed in every bay with the deflectors max of 12" below deck?

Thanks for your replies in advance,
Phil

We have had inspectors require that mineral wool be placed in the gaps formed by the corrugated deck.

"We have had inspectors require that mineral wool be placed in the gaps formed by the corrugated deck." - Would'nt that min wool fall out over time, and/or when it gets hit by the 30 mph updraft from a storage fire plume? I know you did it for them, not on your own accord, but this does not seem logical to me.

I have never worried about those corrugations much, but then again in my area we rarely have that type of construction for mfg/warehousing. I live in the land of plywood on open web steeel bar joists. Its a smooth ceiling as far as defelector distances are concerned. It's also fairly simple to keep the heads on center, in between the 8 ft on center bar joists.

I'll offer the same answer I offer every designer when asked these questions: send me a plan view and a cross-sectional detail. I've learned that regional constructional terms can inhibit the communication.

stookeyfpe ... I can definitely get you that info if you want to take a look at it. Let me know if you do and how best to get it to you.

Thanks everyone for your input so far.

Phil
