Flat slabs and foundations
New punching shear reinforcement systems
The structural design of flat slab systems is usually governed by the punching shear resistance of the slab. To achieve a sufficient punching shear resistance at reasonable slab thickness, shear reinforcement often cannot be avoided. The upper bound of the punching shear resistance is characterised by a concrete crushing located directly at the column face. To strengthen the highly stressed portion of the slab around the column, pre-cast fibre-reinforced Ultra High Performance Concrete (UHPC) units were installed in the compression zone, replacing the normal strength concrete (NSC).
