Wood Pole Structures For Electrical Transmission Lines

Prepared by the Task Committee on Wood Pole Structures for Electrical Transmission Lines of the Committee on Electrical Transmission Structures of the Structural Engineering Institute of ASCE. Wood Pole Structures for Electrical Transmission Lines: Recommended Practice for Design and Use, MOP 141, provides comprehensive knowledge of the principles and methods for the design and use of wood poles for overhead utility line structures. The use of wood pole structures, properly designed utilizing consistent structural engineering principles, may provide a simple, cost effective, and more resilient option than some of the other pole materials commonly used. This manual examinesStructural configurations and pole applications;Critical factors and design considerations specific to wood pole structures;Mechanical properties, applicable standards and specifications used to manufacture wood poles;Wood pole foundations and anchoring;Construction of wood pole structures; andInspection and maintenance of wood pole structures and lines. This Manual of Practice will be valuable to engineers involved in utility, electrical, and structural engineering.

MOP 141 provides a vital overview on the design and use of wood poles for overhead utility line structures using sound engineering practices.

This book covers structural and foundation systems used in high-voltage transmission lines, conductors, insulators, hardware and component assembly. In most developing countries, the term “transmission structures” usually means lattice steel towers. The term actually includes a vast range of structural systems and configurations of various materials such as wood, steel, concrete and composites. This book discusses those systems along with associated topics such as structure functions and configurations, load cases for design, analysis techniques, structure and foundation modeling, design deliverables and latest advances in the field. In the foundations section, theories related to direct embedment, drilled shaf ts, spread foundations and anchors are discussed in detail. Featuring worked out design problems for students, the book is aimed at students, practicing engineers, researchers and academics. It contains beneficial information for those involved in the design and maintenance of transmission line structures and foundations. For those in academia, it will be an adequate text-book / design guide for graduate-level courses on the topic. Engineers and managers at utilities and electrical corporations will find the book a useful reference at work.

MOP 91 describes the engineering considerations involved in designing guyed structures to support electric transmission lines.

This collection contains 36 papers on structural issues in the electrical transmission industry that were presented at the 2006 Electrical Transmission Conference, held in Birmingham, Alabama, October 15-19, 2006.

This Standard provides a uniform basis for the design, detailing, fabrication, testing, assembly, and erection of steel tubular structures for electrical transmission poles. These guidelines apply to cold-formed single- and multipole tubular steel structures that support overhead transmission lines. The design parameters are applicable to guyed and self-supporting structures using a variety of foundations, including concrete caissons, steel piling, and direct embedment. Standard ASCE/SEI 48-11 replaces the previous edition (ASCE/SEI 48-05) and revises some formulas that are based on other current industry standards. This Standard includes a detailed commentary and appendixes with explanatory and supplementary information. This Standard will be a primary reference for structural engineers and construction managers involved in designing and building electrical transmission lines, as well as engineers and others involved in the electric power transmission industry.
