The temperature of the rubber has an influence on the performance degradation of rubber bridge bearings, since thermal oxidation is one of the important deterioration factors for rubber. To evaluate the long-term aging of rubber bridge bearings accurately, it is important to understand the temperature of rubber bridge bearings in an installation enviromnent. In this study, to understand the solar radiation effect on long-term performance of rubber bridge bearing, the temperature of the bearing and global solar radiation were measured for one year for a bearing installed in outside environments. Based on the measured data, an empirical relationship between the internal bearing temperature and solar radiation was obtained. In addition, the long-term increase of the equivalent shear stiffness of a rubber bridge bearing was estimated by including solar radiation effect on bearing temperature.The 24th KKCNN Symposium on Civil Engineering, December 14-16, 2011, Hyogo, Japa
