Ambient noise records, processed through spectral ratio techniques were used to assess the dynamic properties of a sample survey of both reinforced concrete and masonry buildings. Soil-structure interactionswere also investigated using simple 1D modeling to evaluate site amplifications, comparing the results with target spectra postulated by Eurocode8 requirements. The experimental periods obtainedare always lower than those proposed by the building regulations. Therefore one has to pay attention in estimating seismic actions, particularly in those sites of the urban area where there are outcrops of either volcanic products or soft coarse materials.

Abstract

Soil-structure interactionswere also investigated using simple 1D modeling to evaluate site amplifications, comparing the results with target spectra postulated by Eurocode8 requirements. The experimental periods obtainedare always lower than those proposed by the building regulations. Therefore one has to pay attention in estimating seismic actions, particularly in those sites of the urban area where there are outcrops of either volcanic products or soft coarse materials.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
