| Abstract: | Experimental study is an important way to obtain the ultimate strength of fixed offshore platforms. A typical fixed offshore platform located in Gulf of Mexico was taken as the prototype, and the ultimate strength of the experimental model was studied according to geometric similarity criterion and stiffness similarity criterion. The results calculated by the nonlinear finite element method(ANSYS) were compared with the experimental results. The experimental results show that the nonlinear finite element method can calculate the ultimate strength of fixed offshore platforms effectively. |
