A three-stories, base-isolated building located in Rapolla (Potenza, Italy) was tested with a snap-back experiment. Free-field measures were performed using 3D seismometers, located at 10 and 50 m from the buildings in direction of motion and at 10 m from the building in direction transverse to the motion. At each measurement point it was possible to separate the soil amplification effects from two source terms, due to the base-isolated building and to the reaction block. The ground motion was noticeable: at 10 m in the longitudinal direction it was comparable with a small size, near-field earthquake.

Abstract
A three-stories, base-isolated building located in Rapolla (Potenza, Italy) was tested with a snap-back experiment. Free-field measures were performed using 3D seismometers, located at 10 and 50 m from the buildings in direction of motion and at 10 m from the building in direction transverse to the motion. At each measurement point it was possible to separate the soil amplification effects from two source terms, due to the base-isolated building and to the reaction block. The ground motion was noticeable: at 10 m in the longitudinal direction it was comparable with a small size, near-field earthquake.File in questo prodotto:
