How does the load capacity for a reinforced concrete slab depend on the thickness of the slab?
Let's suppose that we have the following constants:
- concrete quality (including the maximum compression resistance)
- same rebars (E.g.: mash of 4/100 mm)
- the rebars are at 35 mm from the bottom of the slab
- the load is constant in every point of the slab
Firstly let's suppose that the slab has a thickness of:
100 mm and supports a constant load (permanent: screed, ceramic tiles + temporary: objects, people) of 250 kg/m^2 (2.5 N/m^2).
How to determine the load capacity for points 2 and 3 based on point 1?
P.S.: The example is just to emphasize the idea. I'd like to have a more general solution.
