The purpose of this study is to evaluate the influence of aged rubber bearings on the seismic response of single steel bridge piers. Firstly, the relationship between ageing and base-isolated rubber bearings' long-term performance is studied. Then the steel bridge piers with base-isolated rubber bearings are modeled as two-degree of freedom systems, and through dynamic analysis the response and damage of the structures are calculated. Next, the rubber bearing is replaced by an aged one and the seismic performance of the pier is evaluated again. The influence of rubber bearing's ageing is compared and discussed. Finally, a procedure to determine the maintenance strategy of a base-isolated rubber bearing is proposed based on the long-term seismic performance of the steel bridge pier.}, pages = {537--546}, title = {Seismic Response of Steel Bridge Piers with Aged Base-Isolated Rubber Bearing}, volume = {52A}, year = {2006} }
