In the present paper, a point estimate procedure is proposed for the evaluation of stochastic response uncertainty due to parameter uncertainties, in which the nonlinear stochastic response including parameter uncertainties is obtained by several repetitions of stochastic response analysis under given parameters. The proposed procedure can be easily performed without conducting sensitivity analysis, which is considered to be one of the primary difficulties associated with conventional methods. A numerical example of a 15F framed structure that takes into account uncertainties of 4 structural parameters and 2 excitation characteristics is performed, based on which the procedure is investigated and the effects of parameter uncertainties are discussed.
