Title: Improvements in the Long Term Durability of Bearings in Bridges, Especially of PTFE Slide Bearings
Author(s): W. Kauschke and M. Baigent

Appears on pages(s): 577-612
Keywords: bridge bearings; durability; evaluation; installing; loads (forces); plastics, polymers, and resins; structural design; Design
Abstract:PTFE is now the most commonly used sliding material used in bridge bearings throughout the world. However, achieving the full advantages of its use over more traditional materials requires careful detailed design. The design and manufacture of PTFE bridge bearings has become a specialty field. Some critical features in the design of PTFE bridge bearings are described. Experimental work on actual structures is described, as well as the calculations made of the life of PTFE surfaces in bearings and their rotational characteristics. Suggestions for further investigations are made.
