ABSTRACT
Two major design methodologies adopted worldwide for the design of Reinforced Soil (RS) walls are the Allowable Stress Design (ASD) and the Load and Resistance Factor Design (LRFD). The two design methodologies use different approaches to ensure stability of the structure. This may result in different design outputs of the RS wall. A parametric study is performed using the widely used commercial software MSEW to understand any potential differences in the designs using ASD and LRFD methods. RS walls having segmental panel fascia with Geostrap reinforcement, and modular blocks fascia with Geogrid reinforcements are studied. It is observed that the LRFD method demands more reinforcement length in Geogrid-block arrangement, whereas the difference is negligible for Geostrap-panel arrangement.
