A DYNAMIC STOCHASTIC FINITE ELEMENT METHOD |
| |
| Abstract: | The dynamic stochastic finite element method, a new random numerical method, is developed for analyzing the stochastic dynamic response of structures with random parameters. A dynamic shape function with structural frequency is adopted to describe the displacement field under dynamic load. The basic concepts and the relevant formulae of the method are expounded in this paper. Numerical example shows that the proposed method is superior to common stochastic finite element method in the efficiency of calculation and the accuracy of solutions. Hence, the method could be applied to analyze random dynamic responses of practical engineering structures. |
