Abstract: The ViBa is a massive structure hosted in a box within the soil and tuned to reduce the vibrations of existing structures in the event of seismic action.It exploits the wellestablished Structure-Soil Structure Interaction (SSSI) mechanism, thereby protecting the built environment in a non-invasive way through its radiated wave field.The efficiency of the ViBa has been proven to date through theoretical, numerical and experimental studies, but it has not yet been tested on a large shake table.Preliminary experimental tests on the 4m × 4m shake table at Fuzhou University have been undertaken for the first time to test the efficiency of the ViBa technology for the seismic protection on a realistic case study.A 1:100 model of a Fujan Tulou has been selected for this application.The shake table tests focused on the efficiency of the ViBa buried in the 2m × 2m × 2m soil box filled with sand.Response-spectrum-compatible ground motion time histories consistent with the Chinese response spectrum have been simulated through a stochastic approach and used for the test.Preliminary results, herein presented, show the Vibrating Barrier did reduce the base acceleration of the Tulou. 1
