Research Abstract

1.The characteristics of gusty winds due to two typhoons, No.17 and 19 of 1991, passed through northern Kyushu are comparatively reported using the measurement records at 24 meteorological stations in Kyushu area. Gust factors at many of the stations exceeded 2 in both typhoons. The turbulent intensities at the stations were estimated to be more than 30%.
2.A new idea was discussed for improving aerodynamic instability of closed and open decks of PC cable- stayed bridge decks. The separation from a leeward separation point is controlled by a separated flow from a windward separation point. By using this method, non-streamlined shape deck can be chosen as the PC cable- stayed bridge girder and this method makes it possible to reduce the dead load of girder.
3.The stability of bridge girders was examined, and every girder satisfied the required wind speed in their wind resistant design. For suppressing galloping of a steel pylon, a tuned mass damper has been installed near its top since erection. Rain-wind induced vibrations of cables were observed on a bridge during construction, and a pair of oil dampers has been installed near the lower end of every cable.
