Current pseudo-static analysis of slopes requires the selection of an equivalent seismic coefficient keq that is demanded to globally represent the effects of the transient seismic action on the slope. In the paper a rational approach for the selection of keq is proposed introducing an equivalence between the pseudo-static analysis and the displacement-based approach. The procedure for the evaluation of keq was developed for the simple scheme of infinite slope assuming that the magnitude of earthquake-induced displacements represents a proper quantity for assessing the seismic stability of slopes.

Abstract
Current pseudo-static analysis of slopes requires the selection of an equivalent seismic coefficient keq that is demanded to globally represent the effects of the transient seismic action on the slope. In the paper a rational approach for the selection of keq is proposed introducing an equivalence between the pseudo-static analysis and the displacement-based approach. The procedure for the evaluation of keq was developed for the simple scheme of infinite slope assuming that the magnitude of earthquake-induced displacements represents a proper quantity for assessing the seismic stability of slopes.File in questo prodotto:
