Various anchors are used to withstand uplift forces for offshore and onshore structures on which research is going on for almost the last six decades. In the present study, it has been attempted to obtain the responses of inclined anchors based on numerical studies. Uplift capacities of model anchor plates having dimensions of 0.025 m × 0.025 m, 0.050 m × 0.050 m, and 0.075 m × 0.075 m with embedment ratios of 1, 2, and 3 and inclination angles 30°, 45°, and 60° with vertical, have been obtained under cyclic loading with 0.2 Hz, 0.5 Hz frequency and 0.002 m, 0.005 m amplitude. The soil bed has been made of locally available clay and the anchors are of mild steel. The numerical analysis has been carried out by ABAQUS, considering all relevant parameters of soil, plate size and inclination angle, and embedment ratio of anchor and also for different frequencies and amplitudes of loading. The variation of ultimate pullout capacity has been studied by varying these parameters. It has been observed that the ultimate capacity under pullout increases significantly with increase in the dimensions of the plate, the embedment ratio, and also the angle of inclination of the anchor with vertical.
