Abstract:
The bearing capacity under punching shear has been addressed in a seriesof experiments. Three types of shear reinforcement of the stirrups type have beenopted as well as the most suitable position of the shear reinforcement. Reinforcementquantities have been modified versus code requirements. Tests results indicate that thesuggested shear reinforcement performed very well. Some requirements in the twoNorth American Codes appear to be conservative compared to the European codes.Bearing capacity assessment in some codes appears to be conservative (bearing inmind, however, that a variety of additional considerations are taken while codedrafting) . Behavior in serviceability was very satisfactory.
