It has been realized that the effect of the parameter uncertainties may be very important even dominant in structural reliability analysis and an important focus in recent research has been to incorporate these parameter uncertainties. In this paper, the reliability problem with consideration of parameter uncertainties is expressed as the integration in the total probability theorem, a general performance function is proposed for solving the integration and the FORM algorithm corresponding to it is deduced which can be applied to incorporate the uncertainty expressed not only as continuous but also as discrete probabilistic variables, in time-invariant or time-variant structural reliability. The geometric means and the theoretical substance are investigated and the influences of parameter uncertainties are discussed through some examples. It has been proved that the proposed method has advantages in both computing efficiency and precision.
