ABSTRACT: An extensive numerical analysis on the seismic site effects due to local topographical and geotechnical characteristics is carried out. Two dimensional (2D) configurations under incidence of vertically propagating SV waves is modeled with the aid of HYBRID program, combining finite elements in the near field and boundary elements in the far field. A parametric study is conducted to examine the combined effects of topography and geology on the amplification of the response spectrum at various points across the valley. The influence of different parameters is considered, such as filling ratios (from empty to full valleys), impedance contrasts between bedrock and sediments, and dimensions. Finally, some criteria are proposed in terms of engineering applications to assess the spectral response at the surface of sedimentary valleys.
