| 内容記述 | This paper focuses on the aged rubber bearing’s influence on the seismic response of base-isolated steel piers. The long-term properties of the natural rubber material are investigated through a series of accelerated exposure tests. Based on the test results, the aged rubber bearing is modeled considering the ageing degree in the outer regions, and the performances are predicted precisely using the finite element method. It shows that the shear stiffness of the rubber bearing increases over time. Then, the study on the seismic response of steel piers equipped with aged rubber bearings is carried out. The results prove that the ageing of the rubber bearing has large effects on the seismic response of the isolated bridges. Generally, the damage degree of the steel pier upgrades to a higher level if the shear stiffness of the bearing increases by 20%, which is crucial from the design point of view. | |||||
