Abstract

This paper integrates a Monte Carlo Simulation (MCS)-based reliability based design (RBD) approach (namely the expanded RBD approach) for foundations with an efficient MCS method called Subset Simulation to improve efficiency and resolution at small probability levels. Equations are derived and implemented in a commonly-Available spreadsheet environment to effectively remove the hurdle of reliability computational algorithm and make the proposed approach available to geotechnical practitioners. The proposed approach is illustrated through a drilled shaft design example. It is shown that the proposed approach provides results that are consistent with those from previous studies and significantly improves the efficiency and resolution at small probability levels. Subset Simulation enhances the expanded RBD approach in the design situations with a small target failure probability.
