Evaluation of the ground motion amplification at poggio picenze (Italy)

Abstract

The study presented here evaluates the ground motion amplification effects at the site of San Felice Martire church, a historical construction located at Poggio Picenze (L’Aquila, Italy). To characterize the soil profile at the site of investigation field geological observations, boreholes and geophysical tests from previous campaigns were gathered. Dynamic soil properties of the identified soil profile were obtained by the test results from selected literature. Then, the amplification effects at San Felice church’s site was estimated using fully 1D stochastic site response analyses and for the object motion seven real records compatible to the Italian codebased spectrum referred to 475-year return period. The set of real records was downloaded from SEISM-HOME web portal. The stochastic analyses allowed to simulate 1,000 different asoil profiles and to run 1,000 simulations, taking into account the inherent variability and uncertainty in the soil profile and on the seismic demand.
