How can punching shear failure are characterised in bearing capacity?

Punching Shear Failure

This mode of failure is characterised by large deformations beneath the footing and practically no movement adjacent to it as in figure. There is no heaving of the ground surface away from the edges, no tilting of the footing, and no adequately defined local-settlement curve. It will occur m a soils of high compressibility (loose granular and sensitive cohesive soils) if the foundation is located at considerable depth.

Punching Shear Failure

In general, the mode of failure depends on the compressibility of the soil and the depth of the foundation relative to its breadth. Theoretical methods are based on the general shear type of failure and may be rational due to the fact that the amount of settlement necessary for local or punching shear types of failure to occur is beyond permissible limits for most structures, and also because analytic solutions for other cases are not available.
