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 examines Structural 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; and Inspection and maintenance of wood pole structures and lines. This Manual of Practice will be valuable to engineers involved in utility, electrical, and structural engineering.
