The present research aims at estimating geological effects induced from the seismic sequence in the municipality of Romagnano al Monte (Salerno, Italy), strongly damaged by the Irpinia earthquake which occurred in 1980. Structural and typological characterization of different samples of buildings has been undertaken according to the EMS-98 scale. The vulnerability assessment of the built-up area has been carried out through an appropriate vulnerability form conceived for masonry building compounds. In addition, a masonry building within a construction aggregate, representative of the class of buildings surveyed, has been selected as a case study. It has been investigated by numerical non-linear analyses using a macro-element approach. Subsequently, to quantify the expected damage, the mechanical fragility curves of the case study building have been presented. Finally, based on the seismic microzonation of the study area, a quantitative assessment of the local seismic response has been undertaken using proper amplification factors to foresee the expected losses more correctly aiming at an appropriate seismic risk mitigation plan.

Abstract
The present research aims at estimating geological effects induced from the seismic sequence in the municipality of Romagnano al Monte (Salerno, Italy), strongly damaged by the Irpinia earthquake which occurred in 1980. Structural and typological characterization of different samples of buildings has been undertaken according to the EMS-98 scale. The vulnerability assessment of the built-up area has been carried out through an appropriate vulnerability form conceived for masonry building compounds. In addition, a masonry building within a construction aggregate, representative of the class of buildings surveyed, has been selected as a case study. It has been investigated by numerical non-linear analyses using a macro-element approach. Subsequently, to quantify the expected damage, the mechanical fragility curves of the case study building have been presented. Finally, based on the seismic microzonation of the study area, a quantitative assessment of the local seismic response has been undertaken using proper amplification factors to foresee the expected losses more correctly aiming at an appropriate seismic risk mitigation plan.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
