Skirted foundation is widely applied in the design of offshore structures. A large number of studies have been carried out to examine the failure envelope of the skirted foundation, but most of them focused on the static loading conditions without considering the effect of cyclic load and providing cyclic failure envelopes. Therefore, this paper proposes a numerical framework to predict the cyclic bearing capacity of the skirted foundation based on the dynamic strength curves and the probe loading method, which is modified so that it can be applied to the cyclic failure envelope calculation. It was found that the cyclic uniaxial capacity is affected by initial average load, number of cycles, and cyclic load amplitude. Cyclic load has a limited impact on the shapes of the failure envelope under combined loading and the degree of its scaling is related to the cyclic degradation ratio controlled by the dynamic strength curves.
