Multi modes coupling galloping of slender structures

Tóm tắt


    The paper presents a general theoretical framework for galloping analysis of slender structures, taking into account the coupling among modes, the modes shapes, and the variation along the structure of mass per unit length and mean wind velocity. The theory is then applied to a real structure. In the galloping analysis, aerodynamic coefficients are obtained from wind tunnel tests. The results of the analysis show crucial points different from conventional analysis.
