Correct interpretation of static calculation for garage (reinforcement...)

…whereas I can't make much sense of your statement if you don't write how it is supposed to be heard correctly… Tiles will be placed on the ceiling, as it will be walkable. Maybe that's why he wrote it that way?

The underside is crucial, where the statically necessary reinforcement is located. XC3 - open halls and garages - would be applicable there. So provide one centimeter more concrete cover on the underside. However, the reinforcement is still sufficient because it was calculated as one-way, but the slab rests on four sides and a Q-mat was chosen instead of an R-mat.

The answer with the Q-mats can be quite correct (not recalculated), but this only applies if the joints of the mats are designed as load-bearing joints (approx. 3 mesh overlap), however, there is no information on this.

Ok, thanks. We will take your comments into consideration.
