Aerodynamic characteristics of super long-span bridges with slotted box girder

Sato, H. / Kusuhara, S. / Ogi, K. / Matsufuji, H.

Aerodynamic stability is one of the most important themes in the design of super long-span bridges. To improve the aerodynamic stability of super long-span bridges, a series of wind tunnel studies and analytical studies were conducted, and it was found that a slot at the center of a girder was effective to improve the aerodynamic stability. The relationship between flutter characteristics and unsteady aerodynamic forces was discussed, and it was found that the flutter characteristics were closely correlated with the unsteady aerodynamic force coefficients M_ZI L_{theta R}/M_{theta I} and M_{theta R}.
