The purpose of this study is to investigate surface-wave isolation by periodic piles from the perspective of attenuation zones. There are three major components. The first is the …
Artificial soils engineered with periodic or resonant structures, also referred as “seismic metamaterials” have been investigated for earthquake mitigation applications. In particular …
In recent years, a new type of seismic isolation system which exploits the filtering effect of bandgaps, named Periodic Foundation, has been proposed to isolate the upper structure …

Surface wave manipulation in periodic trench barriers based on real band structures has its inherent limitations. This work revisits this problem from the perspective of complex band …
This paper proposes a novel multidimensional composite periodic foundation for seismic isolation. The composite periodic foundation achieves multidimensional attenuation by …
This paper studies periodically arranged seismic barriers consisting of finite and infinite lattices to mitigate seismic surface waves in layered soils. Using Bloch-Flouquet theory …
