Good morning,
I'm looking at a concrete pump station in south Florida. The wind pressures are reaching 83 psf (gross uplift) on the roof. I plan on using a precast concrete hollow core deck that will span 28 feet.
Anyone have a feel for when it's a good idea to just use a heavy deck, rather than top slab resteel? An 8" hollow core slab will span 28 feet, but only weights 62 psf. We are the design engineers for the building, not the actual deck. I just want to make sure we show something practical.
