Punching shear reinforcement with increased bond resistance

Flat slabs with lattice girders as semi-precast construction system feature horizontal composite joints between the semi-precast concrete slabs and the in-situ concrete topping. Both the punching shear resistance and the load-bearing capacity of the composite joint have to be ensured for these floor slabs. Using the Filigran punching shear reinforcement not only increases the punching shear resistance, but also the maximum resistance of the composite joint.  A faultless composite joint in the highly loaded punching shear area is the prerequisite for an equivalent load-bearing capacity of...
