Design Of Guyed Electrical Transmission Structures

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

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.

Provides requirements for the design of guyed and self-supporting latticed steel electrical transmission structures, applicable for hot-rolled and cold-formed steel shapes. This title outlines analysis techniques for the geometrical configurations. Procedures for the design of individual members reflect experience and test data on steels.

Prepared by the Design of Steel Transmission Towers Standards Committee of the Codes and Standards Activities Division of the Structural Engineering Institute of ASCE This standard provides requirements for the design, fabrication, and testing of members and connections for latticed steel electrical transmission structures. Covering guyed and self-supporting structures, these requirements are applicable to hot-rolled and cold-formed steel shapes. The standard specifies the design criteria for structure components--members, connections, and guys--to resist design-factored loads at stresses approaching yielding, buckling, or fracture. This new edition, which replaces the previous Standard ASCE 10-97, presents minor changes to the design requirements and introduces new sections on redundant members, welded angles, anchor bolts with base plates on leveling nuts, and post angle member splices. Topics include: loading, geometry, and analysis; design of members, including compression members, tension members, and beams; design of connections, including fasteners, minimum distances, and attachment holes; detailing and fabrication; full-scale structure testing; structural members and connections used in foundations; and quality assurance and quality control. A detailed commentary contains explanatory and supplementary information to assist users of the standard. In addition, one appendix offers 17 design examples, and a new appendix offers guidance for evaluating older (legacy) electrical transmission towers. Standard ASCE/SEI 10-15 is a primary reference for structural engineers designing latticed steel electrical transmission structures, as well as for other engineers, inspectors, and utility officials involved in the electric power transmission industry.

Part of the second edition of The Electric Power Engineering Handbook, Electric Power Generation, Transmission, and Distribution offers focused and detailed coverage of all aspects concerning the conventional and nonconventional methods of power generation, transmission and distribution systems, electric power utilization, and power quality.

This collection contains 46 papers discussing electrical transmission line engineering presented at the Electrical Transmission in a New Age Conference, held in Omaha, Nebraska, on September 9-12, 2002.

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.
