Thumbs up suspended Garage Floor - How thick?

I am building a garage that has a suspended floor because it is being built on a hillside. The dimensions of the garage is 24' x 32'. The floor will be setting on a block wall, suspended above the ground. How thick should I make the floor? Should I put an I-Beam in the center for support? I am using rebar for added strenghth but I am going to be parking my full size pick up truck on the floor and I want to be sure the floor does not crack. Any suggestions?

The framing or support formation for the floor will require engineering to support a concrete floor and the load for it. Usually, formed in place concrete floors are about 6 inches thick. They require the equivalent in support pillars as a conventional wooden for the load.

I would consider a formed in place concrete floor above a crawlspace to be a task for an engineer to design. Your building code may require that very person.

Hope this helps.
