A new reliability-based design approach based on limit-state factor
Recently, reliability-based design approaches emerge as a more reasonable and rigorous way of handling uncertainties. In particular, design approaches based on load and resistance factors (LRFD methods) are increasingly popular. However, for geotechnical problems, it is sometimes not trivial to discriminate loads from resistances. The implementation of LRFD methods seems problematic for these cases. In this paper, a completely different view is taken for reliability-based design. It is shown that sophisticated reliability-based design can be achieved with a single factor, called the limit-state factor. Moreover, the new approach does not require discrimination between loads and resistances but only requires the knowledge of the limit state function. Even more attractively, simple Monte Carlo simulations are sufficient to calibrate the limit-state factor. Several numerical examples are used to verify the proposed approach. The results show that the proposed approach is quite promising.
