Abstract

Todays, Offshore foundations which achieve stability through the putting well in seabed using engineering consideration, are paying considerable attention. By this approuch, in this study combined loading of some kinds of footings studied well to asses the stiffness. Analytical and numerical methods have been applied to have an comparison in this study. Numerical finite element methods have been used and the results showed that numerical solutions have a good agreement with analytical methods and the errors have been reported.
