IEEE Draft Guide for Wood Structures Used for Overhead Electric Transmission Lines

The purpose of this guide is to provide a design overview of wood structures used for overhead electric transmission lines. This guide consolidates useful information, methods, and reference materials that define the state of the art in the design of wood pole transmission structures, commonly in the 69 kV through 345 kV range, into one document. This guide addresses application of wood in transmission structures, characteristics of wood, methods of analysis, loadings, connections, non-wood members, erection and framing, quality assurance, electrical considerations, testing and maintenance.
