| Abstract: | Through the wind tunnel test for the sectional mode of Baling River Bridge,the static three-component coefficients and the fluttering characteristics of the main girder of the Bridge were obtained,the eight fluttering derivates of the main girder were identified and the results of the test were analyzed in detail.The analysis and evaluation of the results can be used to guide the design and construction of the Bridge and can also serve as reference to the bridges of similar kind. |
