| Abstract | ||
| The foundations for offshore wind turbines represent the main item either for cost or installation process, and the lateral resistance of tabular piles is the main factor for its design. Therefore, studies for consistent and efficient foundations have become essential for offshore wind turbines when using traditional mono-pile foundations under practical and environmental conditions. This research discusses the increase in the lateral behavior of open tabular piles with the addition of external wings near the ground level with specific dimensions. Four wings were added to the exterior wall of the open-ended pipe pile at equal angles 90 degrees. The wings length varied from 0.25 to 0.5 of the pile diameter. Each wing length is studied with two depths of 1.25, and 2.5 pile diameter. The numerical analysis was verified with published results of centrifugal tests. The successive parametric study discussed the feasibility of the added wings. Inclusive, the resultant load direction was considered as changed between 0 to 45o with 5 degrees to the wings orientation horizontally. | ||
