Abstract

Static and modal analyses of two pipeline suspension bridges owned by American Natural Resources - the Patterson Loop Aerial Crossing (PLAC) with a span of 850 feet (259 meters) and the Avalon Extension Aerial Crossing (AEAC) with a span of 1,008 feet (307 meters) - were performed to determine why wind oscillations of the former occurred in steady 5- to 8-mph (8- to 13-kph) winds and why similar wind oscillations of the latter have never been observed. The analyses of the PLAC indicated that wind oscillations of this bridge were caused by vortex shedding and that a substantial increase in structure damping due to the addition of diagonal cable stays is the primary reason why wind oscillations have not recurred in this bridge.
