WIND LOADING FOR THE DESIGN OF LARGE SCALE OVERHEAD TRANSMISSION LINES IN JAPAN

, , , and .
(1981)

Abstract

This paper describes the results of studies on wind loading for the design of large-scale· overhead transmission lines in Japan such as studies on statistical considerations of strong win<l records, investigations on fluctuation characteristics of natural wind with respect to time and space, and wind tunnel tests on various types of steel towers and conductors. The principal contents of the paper are as follows: - Basic thinking on wind load and design procedures - Dynamic wind pressure for design (basic design wind speed, gust factor, relation between height above ground and gust wind speed) - Reduction in overhead wire wind pressure with span length - Wind force coefficient (for framework and wire)
