| 内容記述 | It is a well-known fact that aging causes shear stiffness of rubber to increase. Rubber bearings commonly used as base-isolators also tend to increase their stiffness over time. To accurately evaluate future seismic performance of a base-isolated bridge, it is, therefore, important to consider the aging effect of rubber bearings. This paper presents a case study to examine the effect of aging of rubber bearings on the seismic response of a base-isolated six-span continuous steel bridge with lead rubber bearings (LRB). The long-term performance of rubber bearings is estimated based on the size of bearing an average temperature of the construction site, and various aging times up to 100 years. Seismic performance of the bridge is evaluated through dynamic analysis of a three-dimensional finite element bridge model. The results show that the aging of rubber bearings causes an increase in the seismic force on the bridge piers, resulting in larger damage in the piers. | |||||
