So, what is the difference between a floor and a floor slab? Seems to me that, in a home for example, the floor joists upon which floor boards are nailed constitute a floor. In the WTC towers, the trusses upon which the concrete slab was poured constitutes THE FLOOR. Without the joists or the trusses to hold the boards or concrete slabs in place, we wouldn't have a FLOOR.
When you press a number in the elevator of an office tower, you are going to a "floor." You are not going to a floor slab. The floor you are visiting includes all the walls, the ceiling and all the contents.
If you want to be understood, please use the proper terminology--which is "floor slab".
