Abstract

Problems in connection with estimation of the reliability of a component modelled by a limit state function including noise or first order discontinuitics are considered. A gradient free adaptive response surface algorithm is developed. The algorithm applies second order polynomial surfaces determined from central composite designs. In a two phase algorithm the second order surface is adjusted to the domain of the most likely failure point and both FORM and SORM estimates are obtained. The algorithm is implemented as a safeguard algorithm so non-converged solutions are avoided. Furthermore, a number of checks on the solutions are suggested and illustrative examples are shown.
