| Abstract: | In this paper,the random features of input earthquake and structural dynamic parameters are si-multaneously considered. The probabilistic finite element method is introduced into the random vibra-tion analysis. A SDOF dynamic system is taken as an example and the effects of different parameters'variability on the dynamic responses and failure probability are investigated. |
