AERODYNAMIC DESIGN OF HIGHWAY STRUCTURES
Flutter, buffeting, vortex-shedding, and wind-rain vibrations are wind phenomena that can damage or destroy bridges. Elongated flexible structures, such as bridge decks, cables, columns, and signposts, are strong enough to resist static wind loads, but often cannot withstand dynamic fluid-structure interactions that create the aeroelastic phenomena previously mentioned. This article describes the aeroelastic phenomena that cause problems and explains the use of wind tunnels to study wind effects on structures. Two bridges that have been examined extensively at the Federal Highway Administration's Vincent Aerodynamics Labortory are the Tacoma Narrows Bridge and the Deer Isle Bridge. The use of full-scale measurements, computer modeling, and climatological studies are discussed as well.
