Cyclic loading could lead to progressive degradation of soil in terms of plastic strain accumulation, pore pressure build up and changes in soil strength and stiffness. The present paper outlines an explicit method to predict the accumulated foundation displacement under cyclic loading. Cyclic contour diagrams, derived from cyclic laboratory tests, are linked to the finite element software PLAXIS by means of a Python interface. The effects of cyclic loading on the accumulation of strain is
