Concrete modelling to predict crushing in

I have seen people modelling the concrete only (in Stadpro) as shell elements, e.g. in a box bridge beam or concrete stairs. Maybe it is not necessary to model the reinforcements! Maybe it is enough to make sure that concrete does not crush in compression (30Mpa) and does not crack in tension (3.5 Mpa).

Compression test on concrete - Civil Engineering

The concrete cube test result will be satisfactory but the concrete in the structure would have a much lower strength. 3.8.CONCRETE COMPACTION: Concrete ingredients when mixed have considerable amount of entrapped air depending on the workability. High workable mixes have lesser entrapped air than low workable mixes.
