Abstract

Authors have been conducted the field observation of large-scale inclined cable model at the Shionomisaki Wind Effect Laboratory of Disaster Prevention Research Institute since 2000. Using a few types of the cable models, their responses have been measured and analyzed especially under seasonal wind of winter and typhoon wind of summer. Then, the rain-wind induced vibration and the galloping like vibration was observed. The mechanism of the second vibration was not completely proved as galloping. However, this result might show the possibility of divergent type vibration at the stay cables. Also, the steady wind force coefficients for inclined cables were investigated using wind tunnel tests.
