| Abstract: |
Bridge bearings represent a small percentage of the overall cost of a bridge, however if improperly designed or installed they can result in the majority of the problems. As a result it is imperative that bridge bearings be easy to install and have a trouble free design. Many types of bridge bearings have been utilized over the years with a mixture of success and failure. One type of device that has had an impressive performance history for over 40 years is the disk bearing. The disk bearing has undergone extensive testing and offers engineers several different innovative design features for curved girders, uplift restraint, high horizontal loading and high rotations. |
