Title: PERFORMANCE OF SLIDING BRIDGE BEARINGS
Accession Number: 00399170
Record Type: Component
Availability: Find a library where document is available Abstract: An experimental program to evaluate the performance of sliding bridge bearings is described. Tests were conducted in a fixture specially constructed to simulate actual field conditions. Vertical load, up to 250 kips, was applied through a roller nest to the top flange of a 33-in.-deep girder directly over the test bearing. A closed-loop hydraulic testing system was used to apply the horizontal (friction) force. Data were accumulated and processed in real time using a microcomputer-based data acquisition system. Results are presented for three types of tetrafluoroethylene (TFE) elements on two steel surfaces with two backing types, and for new and used self-lubricating bronze expansion bearings. Comparison of results with published design recommendations shows that the recommendations are not conservative for certain TFE-type bearings but are adequate for self-lubricating bronze expansion bearings.
