LRFD Resistance Factors for Maryland Retaining Walls

M. S. Aggour

AASHTO, LRFD specifications for retaining walls were summarized and presented in this report. To carry out comparative design between ASD and LRFD specifications, three types of retaining walls that are used by Maryland SHA were analyzed by both the ASD and LRFD methods of design. This provides a guide for engineers who are not familiar with LRFD methodology but are interested in implementing it. A spreadsheet program for the design of three types of retaining walls based on AASHTO LRFD specifications were developed, which will facilitate the design of these walls for different geometry and soil properties. All analyses undertaken dealt only with the external stability of the wall, i.e., its resistance to overturning, sliding and bearing failure.
