PUNCHING SHEAR REINFORCEMENT
As
a cost-saving construction method, flat slabs are extensively used in concrete
construction because in addition to only a tiny amount of formwork, they also
provide optimum space utilization. The use of punching shear reinforcement in
columns enables thin slabs all the way through because it absorbs very high
shear forces. Rapid construction progress is guaranteed as well as the essential
high level of installation safety. For the installation of punching shear reinforcement, different versions are existing for
in-situ concrete and prefabricated slabs:
