Response of a Latticed Transmission Tower to Wind. Final Report.
The report describes the procedures used and the results obtained in a study of the response of a latticed steel transmission line tower to wind loading. The test tower, 110 feet in height, is on a 500-kV line and supports 3 twin-bundle conductors. Strong wind recordings, in digital form on magnetic tape, were obtained for stresses in the tower members, load on the tower from the conductors and overhead groundlines, the longitudinal and transverse swing of the insulators, and wind speed and direction. The results indicate the general nature of how the tower responds to wind loading as well as the dynamic response obtained through random data analysis techniques. Stesses measured in the tower are compared with values obtained by the Bonneville Power Administration computerized tower analysis procedure.
