Abstract Summary
This paper is devoted to a comprehensive review of the performance of circular surface and shallow foundations under combined loading (VHM), and how this can principally be understood in a theoretical framework in the context of plasticity theory. The associated and non associated plasticity in offshore foundation design is presented; further, it is shown that though the provided formulation results in an enhanced complexity in describing plastic potential surface involving several parameters that need to be calibrated (i.e., depending strongly on foundation type and soil strength), special care should be taken when assessing the skirted foundation responses on different loading.
