Filigran punching shear reinforcement newly assessed
The FDB Filigran punching shear reinforcement consists of spatial welded reinforcement elements with optimized geometry. The punching shear resistance of flat slabs is more than doubled by using FDB, featuring an increase by a factor of 2.1 of a reinforced concrete slab without punching shear reinforcement. According to the manufacturer, this increase factor is higher than that of other punching shear systems. This is the outcome of a comparison with stirrups in accordance with current design standards and double-head studs according to European Technical Assessment (Fig. 1).
