Abstract:
Seismic isolation design has been publicly accepted as one of the most effective strategies to reduce seismic threat to (or seismic demand for) the to-be-protected targets including building structures, infrastructure, and equipment. Recently, many studies have aimed to develop nonlinear seismic isolation systems, of which the sloped sliding-type bearing can exhibit the nonlinear behavior by mechanically designing a simple slope for sliding motion. Therefore, this bearing does not have a fixed isolation frequency. In addition, it features that the seismic isolation performance is realized through the sliding mechanism, the inherent self-centering capability is provided through the slope design, and the excellent and stable energy dissipation capability is contributed by the sliding friction. In this study, the equation of motion of the bearing is deduced first. Sensitivity analysis is then performed.
