REDUCTION OF PEAK GROUND ACCELERATION FOR MONUMENTAL BUILDINGS VIA SUBSOIL TREATMENTS – THE CASE STUDY OF VILLA FAVORITA

. This paper explores the possibility to obtain the reduction of seismic actıons on historical buildings through subsoil treatments. The study is motivated by the unsatisfactory degree of protection of many historical buildings from seismic risk, and by the in-adequacy and/or the inability to adopt the reinforcement or base isolation methodologies. The paper, through the seismic subsoil response by 1D modeling of a suitable case study, i.e. the ancient park on the sea of Villa Favorita in Herculaneum, a site well-characterized in terms of geology, stratigraphy, and mechanical properties of the soil; analyze the effects of possible artificial variations of soil properties on the surface seismic sıgnal.
