Abstract
AbstractA fully coupled simplified method that incorporates soil nonlinearity is used to conduct sliding-block analysis of slopes subjected to near-fault pulse-like and nonpulse-like ground motions. The effects of the ground motion pulse on the computed sliding displacements are investigated, and the efficiency of various ground motion intensity measures for predicting the sliding displacement of slopes is evaluated. It is shown that the slope is expected to have larger displacements over shorter time intervals when near-fault ground motions have pulse-like characteristics. Results also indicate that for cases in which the natural period of a slope is close to the period of the pulse of a recorded ground motion, an equivalent wavelet pulse appropriately represents the displacement response of slopes. Predictive models are developed for the sliding displacement of near-fault ground motions using spectral acceleration and peak ground velocity as predictive variables. In addition, it is shown that for certai...
