This technical report analyzes the concrete floor of a service center under loading from transport trailers. Three loading cases are considered: a single axle at the edge of the slab, a single axle at the middle, and a double axle at the middle. Soil pressure and concrete strength requirements are checked. The soil pressure is found to exceed requirements for the first case but meet them for the second and third cases. Allowable settlement is also within standards. Concrete bearing capacity and punching strength are sufficient in all cases.
