Book excerpt: "This work presents the results of model tests and numerical simulations of shallow foundations subjected to cyclic loads typical of offshore loadings. Small-scale model tests on a shallow foundation, subjected alternately to cyclic loads with large and small amplitudes, have shown that the accumulated rotations due to large amplitude loads reduce during later phases with smaller amplitudes. Numerical simulations have revealed that this behaviour of cyclically loaded shallow foundations is quantitatively influenced by the load amplitude and direction, and number of load cycles. This work concludes with a proposal for foundation geometries that efficiently resist offshore cyclic loads."--Page 4 of cover.
