Abstract

Geotechnical design has traditionally been done using working stress design (WSD). Working stress design identifies limit states for a structure, then protects against their occurrence using factors of safety. Load and resistance factor design (LRFD) uses load and resistance factors instead of factors of safety. LRFD also establishes the geotechnical resistance much more precisely than WSD. This research establishes load and resistance factors using reliability analysis and specifically lays out methods of calculation of resistance for four limit states related to MSE wall design: overturning, sliding, reinforcement pullout and reinforcement rupture.
