Abstract

The present study was conducted to obtain a better understanding of the variation rule of compressive mechanical properties of laminated natural bridge bearings under damper and thermal aging condition. A total of 5 specimens were processed in a high-damp and temperature chamber, and one specimen was in natural state. The parameter mainly considered time of damper and thermal aging processing for specimens. The compressive capacity, ultimate compressive strength and compressive elastic modulus of the laminated natural bridge bearings decreased dramatically. The attenuation models conform to reality well which shows that this model is applicable and has vast prospect in assessing the performance of laminated natural bridge bearings under damper and thermal aging condition.
