To understand a daily variation of bearing temperature and examine the effect of solar radiation on the bearing temperature, which is an important piece of information for a long-term performance evaluation of a rubber bearing, field measurements were conducted on a high damping rubber bearing installed in an elevated highway in summer and winter seasons. By using measured solar radiation, a temperature variation in the bearing was examined through the heat transfer analysis. Results from the field measurements show that the difference between the surface temperature and the ambient temperature became significantly large when the surface received direct solar radiation on a sunny day, and that the maximum difference was greater than 20°C. However, on the bearing surface in the shadow, the surface temperature was close to the ambient temperature, and the maximum difference was only about 2°C. The heat transfer analysis indicated that the region where temperature was significantly higher than the ambient temperature due to solar radiation was within about 20 mm from the surface, and that in the inner region the rubber temperature did not differ much from the ambient temperature.
