The FILIGRAN®-Punching-Shear-Reinforcement FDB is the second generation of punching shear reinforcement that has been optimised for flat slabs using the FILIGRAN® construction method. The FDB enables punching loads that are more than doubled (factor 2.1) higher compared to slabs without punching shear reinforcement. A characteristic feature are the diagonal loops which protrude on the upper chord.
