Temperature dependent performance of high load multirotational bridge bearings

Bridge bearings are used to support the weight of the bridge superstructure on the bridge piers. These bearings allow for the bridge to expand and contract during thermal cycles and accommodate the varying forces on the bridge throughout its life. Elastomers within the bearing are flexible enough to allow for these rotation and translation demands while still effectively transferring forces. This study investigates the effects of combined axial forces and rotation demands on two types of bridge bearings for use within Canada. The bearings will also be subjected to extreme cold temperatures that reflect the design demands for Canadian bridges. The experimental and computer modeling results of this study will allow Canam Bridges, the partner organization, to specify safe and efficient bearing designs for Canadian bridges.
