Before the serviceability limit state designs, RF-CONCRETE Surfaces checks the provided reinforcement: The program first uses the internal forces of the serviceability to perform a design similar to the ultimate limit state design. The thus determined statically required reinforcement is compared to the user-defined provided reinforcement.
If the provided reinforcement is smaller than the statically required reinforcement or if the design reveals any non-designable situations, the serviceability limit state designs are not performed. The problematic zones of the surface elements are indicated as being non-designable.
