Abstract

The present study was conducted to obtain a better understanding of the variation rule of mechanical properties of laminated neoprene bridge bearing pads under thermal aging condition using shear tests. A total of 5 specimens were processed in a high-temperature chamber. After that, the specimens were tested subjected to horizontal load. The results of shear tests show that the specimens after thermal aging processing are more probably brittle failure than the standard specimen. Moreover, the exposure of steel plate, cracks and other failure phenomena are more serious than the standard specimen. The attenuation trends of ultimate shear strength, shear elastic modulus of laminated neoprene bridge bearing pads under thermal aging condition accord with power function. The attenuation models conform to reality well which shows that this model is applicable and has vast prospect in assessing the performance of laminated neoprene bridge bearing pads under thermal aging condition.
