The objective of this paper is to propose an algorithms and a frame work of perturbation-based stochastic finite element method for large variation nonlinear dynamic problem of ship frame structure. For this purpose, based on the principle of stochastic virtual work some algorithms and a framework related to stochastic finite element method have been studied. To prove the validity and practicality, a numerical example for nonlinear dynamic problem with large variation was calculated to compare with Monte-Carlo simulation method. The results showed that the approaches proposed herein are feasible and effective for the nonlinear dynamic analysis of structures with random parameters.
