AC Condenser Pad Design Tips
AC Condenser Pad Design Tips
(OP)
Hello All,
I have used Eng-Tips throughout my college career, but this is my first time posting a thread.
I am designing a concrete AC condenser pad. The pad will likely be 42" x 42" x 4" and will contain a foam core to reduce the overall weight. The current target weight is 265 lbs, which is driven by the Florida Hurricane requirements.
I am wondering what basic design features I can incorporate to reduce the risk of cracking. I'd like to keep the cost as low as possible, so I am trying to avoid re-bar. I'm looking more for tips on the shape / geometry of the foam, wall thicknesses of the concrete, etc.

Don't worry about cracking....your slab is small, so shrinkage cracks, assuming a thickness of 4 inches, shouldn't be an issue.
I would thicken the edges to reduce scour/undermining potential.
