Abstract: | Flutter-based selection for the Jiangyin Bridge, a suspension bridge with a main span of 1385 m, was made through a sectional model wind tunnel test. The concept of “buffeting-based selection” of long-span suspended bridges in the preliminary design stage was proposed, and the corresponding method was developed based on the Scanlan buffeting analysis method. Fifteen long-span bridges that have been researched by the authors and other co-researchers were investigated to simplify the method further. Also, the Jiangyin Bridge was taken as an example to show the application of the buffeting-based selection method. |
