✦ Synopsis

Recent research in soil dynamics is directed toward a better understanding of the seismic behavior of soil within the framework of the principles of nonlinear continuum mechanics. The objectives of this paper are: (1) the analysis of seismic response of a volcanic soil at different spots of a hill located in one of islands of the Central Group of Azores Archipel; (2) the in¯uence on the seismic response of increasing peak ground acceleration values; (3) comparison of results from the analytical model with motion recorded during an aftershock of the July 9, 1998 earthquake; (4) the sensitivity of a few model parameters on the response. A ®nite element bidimensional representation using the Drucker±Prager cap model is employed in the study.

The evaluation of seismic response of soil sites constitutes an important problem with respect to groundmotion amplification and soil instability because of liquefaction. The base motion generated during earthquake is a random process. In addition, the soil sites are usually homogenous with randomly

We present a numerical algorithm for the determination of muscle response by the ÿnite element method. Hill's three-element model is used as a basis for our analysis. The model consists of one linear elastic element, coupled in parallel with one non-linear elastic element, and one non-linear contrac
