| Abstract | ||
| In this study a new technology was generated for steel pipe piles to increase their bearing capacity. The technology consists of addition of horizontal screws similar in terms of size and type to the circumferential surfaces of the pile. The additional parts were equal in length and thickness in order to focus on the technology process and response rather than understanding the role of the screws dimensions. The modified pile was constructed in a laboratory physical box model. Pile load test was conducted on both of modified and ordinary steel pipe piles. The pile load test was performed by notable loads and fixed time duration, which might help in terms of transmitted forces from heavy structures. The results of this study showed that the model gained a considerable resistance, which noticed with the settlement magnitude decrease of the modified pile. Significantly, the recorded settlement was reduced because of the addition of horizontal screws. 9.8, 31.3, 33.3 & 35.9 % settlement reductions were obtained for 8.8, 35, 156 & 191 kPa applied stress respectively. | ||
