Punching Shear in Flat Slabs high strength building punching steel plateJul 17, 2014 · Punching Shear in Flat Slabs. A typical flat plate punching shear failure is characterized by the slab failing at the intersection point of the column. This results in the column breaking through the portion of the surrounding slab. This type of failure is one of the most critical problems to consider when determining the thickness of flat plates at the column-slab intersection.
