 note = {From economical point of view, a two-plate-girder bridge section has been examined as abridge section for a long span suspension bridge. The two-plate-girder bridge section of H or π sectioninherently has not good aerodynamic performances, as shown by the accident of the Tacoma NarrowsBridge with H section type bridge girder. On the contrary, in the present paper, it is tried to find thepossibility of the aerodynamic performance improvement of the two-plate-girder bridge section of the πsection by changing the intervals between the two plate girders. Referring to wind tunnel test results, inthe vortex-excited vibration in heaving vibration mode, the on-set wind velocity and the vibrationamplitude decrease with interval between two plate girders, and the flutter on-set wind velocity increases.These results show the possibility of aerodynamic performance improvement of the two-plate-girderbridge section.},
