Experimental and analytical investigations on nonlinear dynamic response of caisson-pile foundations under horizontal excitation

As a deep-water foundation, composite caisson-pile foundation (CCPF) is usually subjected to horizontal dynamic loads and moments due to the complicated marine environment. In this study, model tests were performed on three different types of deep-water foundation, including caisson, caisson with four piles and eight piles to investigate their lateral nonlinear dynamic characteristics under various excitation forces. Meanwhile, the effect of...
