    Using the substructure method, numerical models of pile-soil interaction of diagonal and diamond types of jack-up legs were developed for dynamic response analysis. Wave and current forces acting on the leg were calculated using the modified Morison equation. Wind load was computed using the DNV formula. Modal analysis was performed to estimate the eigenvalues of the structure. The Newmark-beta method was used to calculate the dynamic behaviors of the structure in the time domain analysis. Maximum displacement and bending stress were computed for each type of leg. Reliability analysis was carried out for both types of legs to obtain a reliability index for the uncertainty of input wave periods.
