ABSTRACT
This study is focused on the influence of seasonal variation of the water table depth in the seismic response of a multilayered soil with a building at the surface, taking into account the Soil-Structure Interaction (SSI). The effect of SSI on the seismic response of the building, having frame structure and rigid shallow foundation, is estimated using a one-directional propagation of three-component seismic waves (1D-3C). The model of 1D-3C wave propagation, in a nonlinear multilayered soil profile, is assembled with a multi-story multi-span frame model in a finite element scheme, solved directly. The case study is the area of San Carlo village in Emilia Romagna region (Italy), struck by the 20 May 2012 Mw 5.9 Emilia earthquake. Results are provided in terms of ground motion at the building base, structural deformation, profiles with depth of maximum excess pore water pressure, strains, stresses and motion.
