Journal of Earthquake Engineering Volume 15, Issue 3, March 2011, Pages 404-432 Numerical evaluation of topographic effects at the nicastro ridge in Southern Italy (Article) Pagliaroli, A. , Lanzo, G., D'Elia, B. Department of Structural and Geotechnical Engineering, Sapienza Università di Roma, Via A. Gramsci 53, 00197 Rome, Italy View references (64) Abstract Numerical site response analyses were carried out on the Nicastro ridge in Southern Italy in order to investigate topographic effects. First, the analyses were carried out on a simplified model by employing simple artificial signals, in order to get preliminary physical insights into the two-dimensional phenomena involved. Then, numerical analyses were carried out on a more realistic heterogeneous subsoil model developed on the basis of geotechnical and geophysical investigations. Real accelerograms were selected for these analyses. Particular attention was devoted to separating topographic from stratigraphic amplification. Finally, the topographic amplification factors were compared with literature data and Eurocode 8 recommendations.
