Control of Splitting

The Splitting control can be carried out for prestressed (non hollowcore) elements. It follows the Model Code 2010 (7.13.6.5.4) where is says that no reinforcement against splitting forces is necessary if the distance between the strands/wires (with diameter Ø) and the cover satisfies the minimum values given in this table:
