Seismic Earth Pressure: Pitfalls and Recommendations
Current approaches for seismic design of retaining structures can be broadly characterized as analytical, numerical, or experimental. All three approaches involve simplifying assumptions to provide a tractable solution. Therefore, use of the methods involves interpretation of the output in the context of the underlying assumptions, which necessitates understanding the inputs and their meaning. Misunderstanding the inputs and assumptions often produces poor comparisons amongst the methods when used to “validate” the applicability of a method over another. In addition, comparison of analysis results to case histories and identifying discrepancies in the assumptions is generally not performed in a consistent manner to ascertain the validity of the assumptions used in the analyses. In this light, the focus of this paper is to highlight the consequences of the basic assumptions inherent in the different methods of analysis.
