Experimental Investigation on Wear Resistance of Bushing in Bridge Suspenders
Publication: Journal of Performance of Constructed Facilities
Volume 34, Issue 3
Abstract
A pin connection is often used to join the hangers with the main cable and main girder in a suspension bridge. As the bridge moves under live or wind loads, the pin-connection components are subject to repetitive loading. The loading causes wear to connection components such as bushings; hence, they often have a shorter life span than other bridge components. In this paper, damage of a bushing in a pin connection between the suspender and deck in a suspension bridge is investigated, and laboratory tests are performed to find a more durable material for the bushing. First, damage of pin-connection components in a suspension bridge is introduced. Secondly, laboratory tests are conducted to determine a more durable bushing material. Finally, conclusions are given that could provide reference for maintenance of suspender connection components in similar suspension bridges.
