A LABORATORY EVALUATION OF FULL SIZE ELASTOMERIC BRIDGE BEARING PADS

The results of a series of physical tests conducted on full size elastomeric bridge bearing pads are presented. Various shapes and sizes of pads up to seven square feet in plan area and 5 inches in thickness were subjected to compressive, cycling, creep, translation, rotation, and ultimate strength tests. Test conditions were selected to simulate actual in-service physical environment. Typical pads consisted of 55 durometer neoprene reinforced at 1/2 inch intervals with steel, polyester, or fiberglass reinforcement. All tests were performed at room temperature.
