Frontiers of Structural and Civil Engineering 2012, Volume 6, Issue 1,   Pages 44-52 doi: 10.1007/s11709-012-0138-x

Abstract: Although no single intensity measure is efficient enough for all slope conditions, the spectral accelerationat 1.5 times of the initial slope period and Arias intensity of the input motion are found to be thecharacteristics of the ground motion and thus significantly improve the efficiency over a wide range of slopethe spectral accelerations at multiple spectral periods achieve high efficiency for a wide range of slopeprediction models as well as the ground motion selection criteria for time domain analysis of seismic slope
