- Seismic Reliability Analysis of Isolated Cable-Stayed Bridge Considering Hardening Effect of Seismic Isolator and Uncertain Structural Properties
抄録
In this paper, influence of the hardening effect as well as uncertain structural properties on the seismic reliability of a cable-stayed bridge was investigated. Seismic isolators modeled by a bi-linear model which neglects the hardening effect estimate piers' performance larger or smaller and tower's performance larger than that by a tri-linear model which considers the hardening effect. Compared to the effect of uncertain structural properties, the hardening effect of the seismic isolator has smaller influence on the piers' maximum deformation, but higher influence on the tower's maximum deformation and cumulative damage of both piers and tower as the degree of the hardening becomes larger due to high level earthquake.
