Prestressed concrete slabs consist of composite, uniaxially stressed hollow plates with a width of about 1.20 m. These elements are prestressed with pre-tension in a precast concrete plant. The precasting is usually done with slipformers. Due to the lesser self‑weight of the non‑solid slab and the existing prestress, these precast prestressed hollow core slabs show a lesser deflection than loosly reinforced slabs made of solid concrete.

If I do not specify any basic reinforcement in RF‑CONCRETE Surfaces, I obtain the value X as an additionally required reinforcement. If I enter this value X as the provided basic reinforcement, I correctly do not get any additional required reinforcement.
However, if I enter a lower value than the determined required total reinforcement as the basic reinforcement, the additionally required reinforcement is increased in such a way that the originally required reinforcement content is exceeded. Why?
