Guide for the Design of Aluminum Transmission Towers

The Task Committee on Lightweight Alloys has prepared this guide for the design of transmission towers. The Executive Committee of the Structural Division decided that no specification shall be issued in the name of, nor endorsed by, the Structural Division of ASCE. Specifications may be prepared by Task Committees of the Structural Division, ASCE, working alone or jointly with other groups. This guide is concerned with the design of transmission towers, for all voltage levels, constructed from aluminum in the alloy 6061-T6. The methods may also be extended to cover other alloys. Fasteners are usually bolts of either aluminum or protected steel. Fabrication and testing methods are also considered. The guide should be considered as one means of designing a tower which will sustain the specified ultimate loads without significant permanent deformation.
