AMBIENT MEASUREMENT RESULTS AND DYNAMIC CHARACTERISTICS OF TRUSS TOWER SUPPORTED STEEL CHIMNEYS BY TYPHOON 1721

Typhoon 1721 occurred on October 16th, going south of Japan from October 21st to 22nd, and around 3 o’clock on 23rd, landed around Shizuoka Omaezaki city. The central pressure of typhoon 1721 at landed was 950 hPa, then the maximum wind speed near the center was 41.2 m/s. In this report, wind speed...

Zusammenfassung:Typhoon 1721 occurred on October 16th, going south of Japan from October 21st to 22nd, and around 3 o’clock on 23rd, landed around Shizuoka Omaezaki city. The central pressure of typhoon 1721 at landed was 950 hPa, then the maximum wind speed near the center was 41.2 m/s. In this report, wind speed and direction observation records obtained from an anemometer installed in a truss tower supported steel chimneys are summarized, the dynamic characteristics of the chimneys are evaluated based on the record of the accelerometer, and the results are reported.
