Introduction Seismic anisotropy is often explained in terms of effective media where an ordered ensemble of sub-seismic elements leads to a directional variation of the materials properties. Examples of such systems include aligned cracks or fractures, fine layering and correlated pore space. Therefore, measurements of seismic anisotropy potentially allow insights to physical systems which woul...

Prestressed segmental precast (PC) piers, with insufficient energy dissipation capacity, are seldomly adopted on bridges in seismic areas. To improve the performance of PC this study proposes a functional separation isolation device (FSID), serving as supplementary replaceable device. Full-scale field load tests real-world pier were carried out to qualify type piers. Based results and numerical...

Abstract There is growing demand in industrialized and developing countries to provide people structures with effective earthquake protection. Here, we employ architectured material concepts a bio-inspired approach trail-blaze new path seismic isolation. We develop novel isolator whose unit cell formed by linkages that replicate the bones of human limbs. Deformable tendons connect limb members ...
