Punching shear behavior of footings with a varying amount of punching shear reinforcement
Experimental investigations
The punching shear design provisions for footings and ground slabs were revised with the introduction of Eurocode 2 in Germany. In contrast to previous German codes, the location of the control perimeter has to be determined by iteration minimizing the punching shear capacity, which particularly applies to compact footings. For the design of the punching shear reinforcement, Eurocode 2 introduced a truss model with a strut inclination of 33° and a constant concrete contribution independent of the type of member. Due to safety related concerns, the German Annex to Eurocode 2 (EC2NA) defines...
