In this paper, the sensitivity that reflects the influence of therandom variables on the structure response is studied. By the application of a new concept of sensitivity factor, a new method for calculating the sensitivity factors of the stochastic response based on SFEM is suggested. The example results show that such method is reasonable and worthy of spreading and using in practice. The conclusion may provide reference for analysis of sensitivity of the structure response.
