Prepared by the Reliability-Based Design Committee of the Structural Engineering Institute of ASCE. Reliability-Based Design of Utility Pole Structures provides state-of the-art technical information on the design of utility pole structures. Among other useful features, this manual demonstrates how poles differing in material can be designed to equivalent reliability levels, provides means for quantifying adjusting reliability, offers design incentives for more reliable poles, and facilitates innovation and introduction of new material. With its technically innovative subject matter and detailed design examples, this manual will benefit pole manufacturers as well as electrical, structural, and transmission and distribution engineers.

Prepared by the Task Committee on Fiber-Reinforced Composite Structures for Overhead Lines of the Structural Engineering Institute of ASCE. This Manual details best practices for the use of fiber-reinforced polymer (FRP) products in conductor support applications and FRP poles. Advancements and innovations in FRP and process technologies have resulted in lightweight high-strength FRP materials that are more cost-competitive than traditional construction materials, such as wood, steel, and prestressed concrete. In addition to a description of the advancements and innovations, the differences in performance between FRP structures and wood, steel, or prestressed concrete are also explained. FRP materials are used widely in many applications because they can be engineered to offer important advantages over traditional materials and also offer product engineers extraordinary design latitude. Engineers can choose from a wide range of material systems and processing techniques. FRP structures fall into one of five basic configurations: cantilevered structures; guyed structures; framed structures; combined structures; and latticed tower structures. The manual recommends and provides suggested guidelines for performance-based tests for all FRP poles. It also discusses factors that could affect the performance of FRP poles after installation, suggests field inspection methods, and provides basic maintenance and field repair techniques that can be used to extend the life of FRP poles: environment, UV radiation, temperature, moisture, ice and snow accumulations, fire, chemical exposure, biodegradation, mechanical fatigue, and electrical stress and leakage current.

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.
