AERODYNAMIC STABILITY OF LONG COLUMNS WITH ELASTIC END CONSTRAINTS

This report presents a method for calculating fundamental frequencies and predicting wind-induced responses of long, slender bridge members. The method is illustrated through use of practical examples and predictions are compared with field measurements. The report will be of interest to bridge engineers and researchers involved in the analysis, design, and construction of large bridge structures which contain these members.
