The proposed seismic metamaterial in the form of the optimized tuning fork structure can provide a good attenuation performance with lower steel consumption due to the locally resonant band gaps. Finally, a numerical investigation of the seismic surface wave propagation through an array of tuning fork unit cells has been conducted to verify the seismic shield effects in band gaps. Through the parametric analysis, the vibration frequency of the tuning fork has been optimized to match the primary frequency of the seismic surface wave for enhancing the seismic energy dissipation. The types of eigenmodes with respect to the tuning fork structure have been determined, especially the special eigenmodes different from the traditional column structure. The finite element method was applied to calculate the eigenmodes and the seismic shield effects in the commercial software COMSOL Multiphysics. ObjectiveĪ novel tuning fork-shaped seismic metamaterial has been proposed for the utilization of the peculiar vibration modes of the tuning fork structure as the locally resonant to the dissipation of seismic energy. However, such column structure requires a large amount of rigid material to generate broadband band gaps in the low-frequency range. The unit cell of seismic metamaterials is generally designed as a column structure with a uniform cross-section. The development of seismic metamaterials provides new inspiration for controlling the propagation of seismic waves.
