Seismic Coefficients for Pseudostatic Slope Analysis
1 Senior Staff Engineer, Kleinfelder, Inc., Pleasanton, USA. Email: Professor, University of Idaho, Moscow, USA. Email: World Conference on Earthquake EngineeringVancouver, , CanadaAugust 1-6, 2004 Paper No. 369 Seismic Coefficients FOR Pseudostatic Slope ANALYSISC ristiano MELO1 and Sunil SHARMA2 SUMMARYP seudostatic Analysis is one of the simplest approaches used in earthquake engineering to analyze the seismicresponse of soil embankments and slopes. However, the choice of Seismic Coefficients used in the analysiscan be arbitrary and generally lacks rationale. To investigate this, a parametric study was performed on a soilembankment of varied geometric characteristics and soil properties subjected to three different strong groundmotions obtained during the 1994 Northridge earthquake. The dynamic response of the embankment modelwas used to calculate Seismic coefficient time histories for critical failure surfaces generated throughconventional limit equilibrium Analysis .
