Abstract
- A novel seismic metamaterial plate consisting of two common building materials, which has the advantages of simple structure and easy to realize, is proposed. The seismic metamaterial plate creates a wide bandgap with a relative bandwidth of 1. Using numerical simulation, the bandgap properties of the metamaterial plate both in a free space and on a half space are studied and it is found that the wide bandgap of the free plate is kept even if in half space. Using scaled (1:30) experiments under 1 g conditions and simulations, we study the transmission spectrum under the surface waves incident on the seismic metamaterial plate and verify that it has a good attenuation effect in the corresponding frequency range. This work paves the way to the design of seismic metamaterials allowing an unparalleled control of surface wave propagation. [ABSTRACT FROM AUTHOR]
