EFFECTIVENESS OF FAIRINGS ON A SUSPENSION BRIDGE
This paper describes a study conducted on an existing plate girder suspension bridge that has demonstrated wind response problems during its long service life. Despite many retrofits, the Tacoma Narrows Bridge has suffered significant structural damage during several windstorms. Wind tunnel experiments were carried out to identify the causes. Long-term measurements of bridge response behavior and site wind conditions, as well as analytical studies, were performed in parallel with the experimental work. While special features of the bridge have enabled it to survive, research has shown that the bridge is prone to several wind instabilities. As a result, fairings were designed for and implemented on the bridge. Monitoring of the post-retrofit behavior is continuing. A description of the unique bridge details is provided, and an overview of the investigation is given. Key findings are summarized, and conclusions are drawn.
