Abstract

Based on the semi-analytical flutter derivatives of flexible structure provided by authors(XU Xu, CAO Zhi-yuan. Linear and nonlinear aerodynamic theory of interaction between flexible long structivre and wind, Applied Mathematical and Mechanics, 22(12):1299-1308.),the relationships of the flutter derivatives of slender bridge were investigated, and then their intrinsic relations were validated, by the test data of flutter derivatives of two bridges. The changing of flutter derivatives with the aerodynamic center, notation speed and angles variation were also researched by parametric method. The results not only prove the conectiress of expressions of flutter derivatives given by author, but also indicate that some certain relations exist in them. Tlutirermore, the semi-analytical flutter derivatives are showed to be applicable to the bridge with streamlined cross-section.
