Description

For wind resistant design considering the directional design wind speed and structural characteristics of transmission lines, the accurate wind load evaluation for every wind direction is needed. Namely it is important to consider the dynamic effects of the tower-conductor systems, such as scale and resonance effect, as well as the wind speed influenced by topography and the wind direction. For this purpose, we proposed sub-system wind loads such as wind forces on tower, overhead wires and tension force of overhead wires considering dynamic effects based on gust effect factor method. In addition, we also developed a combination method of sub-system wind loads, based on theoretical study, wind tunnel tests and observations of test lines. Then we enabled the load evaluation corresponding to actual conditions.In this paper, we describe the feature of wind load evaluation method and the comparison results between Sikoku test line observations and predictions.
