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 ...

Seismic isolation is a method of protecting building from earthquake-induced deformations by using isolators and devices under the superstructure. The purpose seismic to reduce earthquake forces transferred ground structure placing energy-absorbing elements between foundation Especially in developing countries, "Geotechnical Isolation (GSI)" system has been proposed as new damages on buildings....
