RELIABILITY ANALYSIS METHOD OF REDUNDANT GEOSYNTHETIC-REINFORCED SOIL WALLS

Abstract

Geosynthetic-reinforced soil walls have system redundant parallel structural system. In this case, failure of one structural component does not lead to collapse of structural system. This paper proposes new reliability analysis method for redundant geosynthetic-reinforced soil walls. Proposed analysis method is based on basic concept that failure of geosynthetic-reinforced soil wall is multiple. In this paper, outline of the analysis method is explained. Estimation method of partial safety factors with considering redundant structural system is also discussed.
