  • AERODYNAMIC STABILIZATION FOR GEOMETRICAL GIRDER SHAPE OF TWO EDGE GIRDERS OF LONG SPAN CABLE STAYED BRIDGES

抄録

This paper describes the fundamental aerodynamic characteristics of two edge girders, which have economical and structural advantages for future long span cable stayed bridges. Especially, for the purpose of the aerodynamic stabilization of two edge girders, the aerodynamic effects of the inclined lower flanges of two-edge girders are investigated by a series of wind tunnel tests, such as the measurement of unsteady aerodynamic forces and free vibration tests. In addition, the adaptable center span of cable stayed bridges with two edge girders is described. As one of conclusions, it was clarified that the geometrical girder shapes and the location of girders sensitively affect on the characteristics of the vortex-induced oscillation and the flutter instability of two edge girders, especially, the inclined lower flanges with two edge girders play an important role on characterizing the aerodynamic stabilization of two edge girders and assist the aerodynamic stability.
