The paper reports the punching shear tests of 14 column footings
of reinforced concrete. The main variables were the concrete
strength, the ratio of flexural reinforcement, the type of anchorage
of the reinforcement, and the type of shear reinforcement. The
tests showed that the concrete strength had a strong influence on
the punching shear strength. The ratio of flexural reinforcement
only slightly influenced the punching shear strength. The type of
anchorage did not influence the punching shear strength. The use
of inclined bent-up bars as shear reinforcement gave higher
punching shear strengths than the use of stirrups
