dc.description.abstract | Pile foundations for offshore structures are subjected to vertical-horizontal load combinations. The current design method separately analyzes horizontal and vertical responses of piles without considerations of the combined effect of the loads on soil-pile interaction. However, there is experimental and numerical evidence that lateral behavior of a pile-soil system can be affected by both axial compression and tension load on the pile. In this study, two single-pile and two tripod-pile centrifuge model tests under different loading conditions were analyzed to investigate the influence of combined loads on the lateral response of soil-pile system. The displacement and the bending moment were measured and analyzed to highlight the behavior of pile-soil system under different loading conditions. The p-y curves for the different tests were calculated and compared to reveal the influence of axial load component on the lateral behavior of soil-pile systems. It is concluded that compared with pure lateral loading, the p-y curves of piles under compression are steeper because of soil densification effect, while the opposite is observed under tension load that is the p-y curves are gentler. | |
