cross section
a structural garage floor has to support as much as 4000 pounds or more distributed over 4 point loads (the tires)
in northern areas, road salt dripping from the car can corrode and weaken the steel reinforcing bars
fortunately, most garage floors are not suspended, but be careful if you find one

Generated explanation

The cross section shows a car on a suspended reinforced-concrete garage floor spanning foundation walls above a basement. Downward arrows illustrate vehicle weight applied through four tire point loads, with the car labeled as weighing 4000 pounds or more. Reinforcing rods are shown near the underside of the slab. The surrounding assembly includes foundation walls, footings, a basement floor, granular base, and perimeter drainage pipes. Annotations warn that road salt dripping from vehicles can corrode and weaken the steel reinforcement, although no actual deterioration is drawn.
