Slab on Metal Deck Construction Joint Spacing
Slab on Metal Deck Construction Joint Spacing
(OP)
Does anyone have a reference for maximum pours for slab on metal deck?
I have seen drawings that seem to indicate 160ft or 10,000 sf.
An exhaustive google search doesnt turn up much.
We recently had a 350 ft building that was placed in one pour and seemed to exhibit cracking with "loud cracking sounds" according to a tenant. I'd like to make sure we are limiting our pours to a realistic amount based on something that can be backed up.
Thanks,
G

If not, doubt if there will be a documented, authoritative source.

TopKnot's last reference (the vulcraft link) only states that EXPANSION joints are needed between 200 to 250 ft. through the entire building....not construction or control joints in the slabs.

Regarding the "loud cracking sounds", could this have been "banging bolts"? How do you know it was slab cracking that was making the noise?
RE: Slab on Metal Deck Construction Joint Spacing
I have several drawing sets from some high end structural companies that put limits on their pours. I want to determine the basis for these limits.
We are aware of bolt banging and the reports do not seem to match the 'shotgun blast' we read about. I hesitate mentioning this here, as to how preposterous this sounds, but the tenant said he saw cracks opening up while hearing the sound! In any case, the sounds have subsided and there have been no reports since.
I am not convinced that our long pour led to this, I just want to do my research to make sure we have our bases covered.
