### Abstract

It is common practice in geotechnical earthquake engineering to estimate seismically-induced slope displacements using Newmark's procedure to integrate the equation of motion for a rigid block sliding on an inclined plane. Possibly, as a result of attributions of damage to relatively large vertical accelerations in recent earthquakes, concerns have been voiced by some investigators on the appropriateness of the classical approach to Newmark analysis which ignores the vertical component of excitation to compute permanent deformations. This paper presents a modified Newmark procedure in which the vertical component of strong ground shaking is incorporated into the analysis. The results of example calculations indicate that, while the classical approach may give reasonable results for homogeneous slopes, caution is warranted in design of slopes with low shear strength values.
