When using FORM and SORM to predict the probability of failure for a structural component a model for the failure function has to exist. For certain structural components a mechanical model for the prediction fo the failure function is no-existing, or, at least, is inadequate. In that case empirical relationships (response surfaces) must be used. In this paper some experience with this not uncommon and reliability problem is reported.
