Load and resistance factors by reliability analysis on reinforced soil walls

Abstract

The paper presented recommended load and resistance factors of limit state design (LSD) for reinforced soil structures using two wedge method. The load and resistance factors for the LSD format are calibrated rigorously using advanced first order and second moment method and Monte Carlo simulation with Latin Hypercube Sampling according to the conventional safety factors. As a result, the load and resistance design factors based on the reliability analysis are independent of soil properties and wall heights but dependent on failure mode .
