we are currently involved in demo-ing just such a structure. (except it was below grade H20 reservoir on land donated by an avid tennis player)
catch was, no one ever used courts as they "felt funny".
the PC DT's were like plying tennis on trampolines.
just a note of caution. not sure under those span distances you can get a stiff enough tee to prevent the bouncy effect that PC tends to have.
maybe you can . . . just a point to ponder in case you haven't !

I am working on a golf car storage building project. We are using a
precast concrete DT's supported by P/C IT's and columns on interior
support lines and P/C wall panels around the perimeter. The structure
is built into a hillside (open on one side only) and the "roof" will
have two tennis courts.
I am concerned about the roof deck system. I presume that the DT's will
be erected un-topped and that the topping slab will be field poured. We
specify tooled/sealed joints to align with all joints between P/C
members. I also presume that a surface with that many joints will not
be desirable as a playing surface for tennis and that an additional
wearing/playing surface slab will be necessary.
The wearing surface (with inevitable water leaking and deterioration
problems) is where I anticipate some problems. My thoughts are that it
would be ideal to place a waterproof membrane over the topped P/C
decking, put a drainage mat of some sort over the membrane, protect the
drainage mat with some sort of protection board and then pour the
wearing/playing surface slab over the protection board. My hunch is
that the wearing slab should "float" on the structural system.
My questions are:
Has anyone had experience with a similar condition?
For drainage of the deck, the entire system will slope at 1"/10' to
scuppers and downspouts. How do I get the water out of the drainage mat
between the structural deck and the wearing slab? (Floor drains,
Any assistance will be greatly appreciated.
