mechanical pad

[Structures33]

hey all - i'm providing a simple, stand alone, exterior mechanical pad to support a 2,500 lb freezer. size and soil not a problem. is it common practice to detail this unreinforced? the footprint is 12.5'x3.5' so it's really not seeing much bending. i have many interior mechanical pad details, all of which are r/f to tie to the slab. this one will not tie to anything and will not be subjected to shaking or vibration.
thanks in advance!

If the slab is on a well compacted base (aggreagate compacted to 95% proctor) and a minimum of 8" thick, I would not have a problem with it.

T&S steel is not really needed for a free standing slab of that size. And if the base is solid and UNIFORM to prevent differential settling, there will be no significant bending.
