Shallow foundations

What is it about?

Bearing capacity of foundations to punching shear in the standing codes is mostly based on experiments on reinforced concrete slabs. The experiments on foundations have been rare so far, and they were performed in laboratories, where soil was simulated in various ways. The goal of this research is to perform the punching shear experiments in the circumstances which are as close as possible to actual conditions both in terms of the foundations, and in terms of the soil. This would provide answers to questions such as what the gradient angle of punching cracks is and what the distribution of pressures on the soil is and its effects on the bearing capacity of foundations to punching shear, which are the fundamental parameters affecting the bearing capacity of foundations to punching shear failures, and there is a large discrepancy between them and the standing codes. Apart from this, the punching shear failure mechanism would be determined, which would indicate the parameters whose influence is dominant in the course of punching shear of foundations and which should be focused on in the further research.
