Abstract: A variance reduction technique for randomly excited nonlinear dynamic systems is proposed. Utilizing the measure transformation method an importance sampling scheme for Ito stochastic differential equations is established which allows -- at least theoretically -- to construct unbiased zero-variance estimators of functionals of the system response. Applying approximate solution techniques as e.g. statistical linearization or cumulant-neglect closure, sub-optimal estimators can be constructed.... (Update)
