Punching shear of column footings

Experimental studies

Summary

Based on a research project conducted by Deutsche Forschungsgemeinschaft (DFG - German Research Foundation) that had been concluded already, ten punching shear tests were carried out on individual footings. The tests primarily investigated the influences resulting from concrete compressive strength, different longitudinal reinforcement ratios, larger slab thicknesses and a punching shear reinforcement. The test results prove that the shear slenderness has an influence on the inclination of the crack formation. The influence of the structural effective head on the punching shear...
