Abstract

This paper presents the comparison of the various methods of analysis of retaining walls under seismic loads. The furthermost usually used methods for the seismic design of retaining walls were considered. A concrete retaining wall was considered and analyzed for the static as well as the seismic loading conditions. It is formed that internal friction angle and soil-wall friction angle affect the stability on the basis of parametric studies. The authors have calculated the factor of safety against sliding and overturning. Two Statics and four dynamic methods for zone four (IV) have been studied and compared for their factor of safety. Amongst the six methods being studied, Choudhury and Nimbalkar [3] came out for maximum factor of safety. Whereas Seed and Whitman [12] with minimum factor of safety. Hence the method used by Choudhury and Nimbalkar is recommended for earthquake prone areas on the basis of this study. It is also found that Seed and Whitman (1970) are more conservative as compared to other methods.

Keywords
