<p>This study investigated the cyclic response of a suction caisson in clay under one-way cyclic loading. The analysis was performed using the nonlinear kinematic hardening model. The finite element model was validated against published centrifuge tests and compared with a numerical analysis from the literature. A parametric study was conducted to assess the influence of the degree of strength non-homogeneity, load inclination angle, and rate of increase in load amplitude. The numerical analysis results revealed that both cumulative displacements and rotations decreased with increasing degree of strength non-homogeneity. Quantitatively, increasing the degree of strength non-homogeneity from 4 to 7 reduced the normalized cumulative resultant displacement after 100 cycles by 78.95%, 79.01%, and 78.32% for load inclinations of 0°, 20°, and 45°, respectively. For a given aspect ratio, the cumulative resultant displacements were found to decrease with an increasing load inclination angle. The greatest cumulative rotations occurred at a specific load inclination angle. The results indicated that both cumulative horizontal and vertical displacements increased at a higher rate of increase in load amplitude. The cumulative resultant displacements and rotations increased by more than seven and eight times, respectively, as the rate of increase in load amplitude increased from 2 to 5.</p>
