Description
With the rapid expansion of urbanization, an increasing number of high-rise structures require protection from earthquake-induced damage through seismic isolation systems. However, current technologies lack effective isolation barriers capable of mitigating horizontal seismic waves. This study proposes an improved ring-resonator Unit Cell (UC) for two-dimensional (2D) periodic materials is proposed based on Bloch–Floquet theory and locally resonant mechanisms. The Wave Finite Element Method (WFEM) and Finite Element Method (FEM) are employed to investigate the Band Gap (BG) characteristics and various wave modes of the UC. Furthermore, the Transmission Loss (TL) of the proposed 2D Ring-Resonator Periodic Materials (RRPM) is validated through numerical simulations. Results demonstrate that the proposed ring-resonator UC exhibits a significantly wider and more effective band gap compared to conventional circular resonator designs.
