A locally resonant seismic metamaterial with a low-frequency broadband bandgap

Key Points

• The low-frequency broadband bandgap allows for effective seismic energy reduction, and enhances structural protection.
• Measured bandgap spans frequencies below 1 Hz, ensuring applicability for various seismic events.
• The study employs a localized resonance design, featuring wave propagation control through metamaterial structures.
• These findings highlight the potential for improved earthquake resilience using seismic metamaterials in infrastructure.
