Abstract

Precise understanding of swinging of the overhead conductor under strong wind condition is essential for the steel tower design. By considering this concurrency of the swinging, it becomes possible to reduce the weight of steel tower, and this leads to a significant cost down effect. In considering this fact, we started to study with a view of establishing a new technique for corrective grasping the relative swinging based on the observation and others of the Test Line, thus reflecting the results on the steel tower assembly design. When we investigated the data on a Shikoku Test Line in a strong wind condition that occurred in the past, we could extract the swinging phenomenon when a typhoon was passed. We then compared the observation data (wind data) obtained at that time with the analytical results obtained by numerical simulation “CAFSS”, by considering up to the variation component of blowing up angle of wind, and obtained a good coincidence between the observation and analysis, as reported in this paper.
