The candidate will deal with novel concepts of periodic metamaterials/metastructures for the vibration mitigation of large structures like nuclear power plants or broad tanks of petrochemical plants subjected to both seismic shear and/or Rayleigh waves. More precisely, novel smart foundations will be designed based on metastructure concepts for vibration mitigation of seismic waves including their vertical components. In addition, and with regard to vibrations due to the impulsive components of the contained fluid, new tanks will be conceived with novel periodic smart foundations endowed with resonators. Moreover, tanks can also be treated as resonating systems by themselves. These novel design concepts will also be explored for other examples of important symmetric structures, like the tanks used in regasification stations. Emphasis will also be given to laboratory testing of prototypes through dynamic actuators and/or shaking tables. The outcome of the research activity will consist in journal papers and prototype isolation devices.
