Sheet Pile wall design using methods in AASHTO LRFD Bridge Design Specifications (2010) is compared in this study to methods in United States Army Corps of Engineers (USACE) Engineering Manual 1110-2-2504 (USACE, 1994). It will be shown that AASHTO (2010) results in a greater embedment depth, mainly due to a safety factor compounded with Load Factors. Simple modifications to the current AASHTO (2010) code provisions code are suggested which have the potential for large cost savings – while achieving a relatively conservative design compared to conventional design methods (USACE) and typical load combinations. Guidance on the selection of load combinations is also provided. Finally, available centrifuge test data for sheet pile walls subjected to earthquake loading are compared to resulting moment demands derived for both AASHTO and USACE methods.
