    Ghayas Ud-din Dar
    This document outlines the topics covered in a course on the design of transmission line structures and foundations. The course covers design criteria and loads on transmission lines, behavior of suspended cables, conductor types and performance, basic structure design, computer modeling and analysis tools, design of various structure types including wood poles, tubular steel poles, concrete poles, wood H-frames and steel latticed towers. It also addresses foundation design for poles, frames and towers as well as guy anchors. The goal is to teach students how to properly design transmission line structures and foundations using codes, standards and computer analysis tools.
