Considering the two options
- build internal wall on top of 10 cm deep concrete slab reinforced with 7.7 mm smooth steel wire mesh
- build internal wall on top of 30 cm deep concrete floor joist reinforced with a 24x24 cm steel cage made of 12 mm deformed steel rebar
What effect do
- the deeper concrete
- the greater amount of steel
in the floor joist have in supporting the weight of the wall (which I assume is treated as a compressive load)?
In both cases assume that the concrete used is the same grade. The wall is not load-bearing, as the overall structure is a reinforced concrete frame.
