摘要

Elastomeric bearings such as rubber bearings frequently used as isolators for bridges deteriorate gradually when they are exposed to radiation or at elevated temperatures. Meanwhile, elastomeric bearings could be damaged by the failure mechanisms of creep and fatigue when they are subjected to external loads. The dynamic resistance of elastomeric bearings is thus reduced due to the changes of their molecular structure caused by environmental or mechanical attacks. As a result, the damping efficiency of isolators made from elastomeric bearings might be dramatically decreased when they are under a cyclic loading of earthquake. This paper mainly aims at investigating the deterioration of dynamic behavior of rubber bearings under variously environmental attacks such as cyclic loads and elevated temperatures. Effects of fatigue and thermal aging on the dynamic behavior of rubber bearings are discussed and presented.
