SEISMIC: Development of Improved Procedures for Seismic Design of Earth Retaining Structures on Conventional and Pile Foundations

Existing Caltrans design procedures for retaining walls are force-based. Preliminary studies using LRFD-based design procedures suggest this approach may be overly conservative. In addition, current design method does not provide guidelines for pile-supported walls. Therefore, new analysis and design procedures are needed. These new analysis tools should ideally be displacement-based, and should be validated with existing experimental data sets and carefully planned additional dynamic and cyclic loading experiments. The new design and analysis tools should be readily applicable to Caltrans practice.
