I have a hollow-core precast slab that was installed circa 1985. We have the structural drawings, that indicate the slab is 6", with a 2" structural topping. The slabs are 2' wide, so we suspect it is a Flexicore. We have the design loads, but unfortunately, the design loads work for even the least stranded hollow-core slab from the 1978 Flexicore safe load tables. In short, we would like to analyze the T624A-D20 strand designation from that very manual, using current ACI criteria. We need to obtain around 10-15 additional psf, and I think we can, but I need to run the numbers to make sure. Can anyone provide asssitance on this, or point to an analysis spreadsheet that could assist? I greatly appreciate your time and consideration.
