Devices such as isolators, dampers and tuned mass dampers are now widely used in the construction industry for earthquake engineering to reduce vibration in new and, in a few cases, existing buildings. However, the use of those vibration control devices implies structural modifications that might be costly of prohibitive. In this context, a novel passive control device called Vibrating Barrier (ViBa) has been recently proposed. The ViBa is a massive structure, hosted in the soil and detached from the other structures, calibrated for absorbing portion of the ground motion input energy. The proposed device is applied to a model of an industrial building. Parametric analyses have been performed considering various soil profiles and mechanical/geometrical properties of the device. Significant reductions of maximum displacements are achieved for short distances and small ViBa damping ratio under harmonic ground motion.
