SEISMIC BEHAVIOR OF A HETEROGENEOUS SOIL WITH UNCERTAIN HEIGHT
This paper deals with the seismic behavior of a heterogeneous multilayered soil profile extending horizontally to infinity, and having random properties. Stochastic soil seismic analysis is carried out via Monte Carlo simulations combined with the Thin Layer Method (TLM). Property of interest is the bedrock depth modeled herein as a random field, by choosing the uniform distribution. The purpose is the investigation of the impact of this uncertainty on the probabilistic seismic response of the soil profile in time and frequency domains. Obtained results indicate that the ariability of soil thickness significantly influences the seismic behavior in time and frequency domains, causing a substantial extension to the frequency content. The analysis carried out in this study indicates that uncertainty in bedrock depth is among parameters that should be incorporated in any stochastic soil dynamics investigation.
