ABSTRACT

Within the last three decades, many experiments were carried out on testing of the punching capacity of footings. The tests differ manly by subsoil simulation. Most of the tests were carried out in a way where soil pressure was modelled by springs and later by a set of hydraulic jacks. In order to know the differences in behaviour of the footings resting on the more realistic soil, several tests were carried out at the university laboratory. Four footings with different shear slenderness resting on 2 m thick gravel cushion were tested for punching. The paper presents obtained results and comparison with the assessed punching resistances using three different models for the prediction of the punching capacity. Using results of further 55 tests that were carried out on different types of the subsoil the model’s safety was assessed for each of the three models.
