Abstract: A general and efficient method is presented for computing failure probabilities for components and systems where the uncertainties are represented by a mixture of random variables and time dependent processes. A formulation as a first-passage problem for a vector process outcrossing a safe set is first applied, conditioning on all the random variables. This leads to a conditional failure probability and a fast integration technique based on a first- or second-order reliability method is then applied to compute the overall failure probability.
