On the Vibration of a Cylindrical Tower Structure Induced by Strong Winds

Abstract

The lateral vibration of a cylindrical tower structure induced by strong wind is presented. We observed the amplitudes of displacement at the top of Kyoto Tower, when Typhoon No.24 passed over the Kinki District in 1965. The typhoon was attended with a maximum peak gust of 51m/sec at the top, and we shall discuss some problems below the mean wind speed of 35.5m/sec. Before the relationship between the amplitudes and the wind speed is clarified, the duration time of the fluctuating wind velocity will be dealt with to fit the characteristics of the structure. In this range of wind speed the maximum amplitude arises at 28m/sec.
