The surging demand for electric power has led to upgrading, designing and building new transmission lines across North America. With the emergence of powerful computer methods for analysis and design, this demand in turn is mandating experienced line designers, structural and geotechnical engineers. With the retirement of one generation of experienced engineers and designers, and regular revisions and updates to various codes and standards, it is becoming vital for the next generation of engineers to become more familiar with the various aspects of analysis, design and installation of transmission structures and foundations. This one-and-a-half-day course is designed to introduce and provide a practical overview of important materials and standards to be considered in transmission structure and foundation design. The first day will cover structural materials and ASCE and RUS standards. The second day will focus on foundation design.    

Learning Outcomes

  1. Discuss various materials and associated ASTM, IEEE and other standards used in building transmission structures and how they are input into analysis software
  2. Identify RUS/USDA Standards for transmission lines, structures and foundations
  3. Examine the difference and process of calculating RUS design parameters vis-à-vis NESC Rules
  4. Discuss various ASCE Standards, Guidelines and Manuals of Practice for transmission structures
  5. Examine current standards for steel, concrete, lattice, guyed and composite transmission structures
  6. Analyze upcoming changes to Steel Transmission Pole Design Standard (ASCE 48)
  7. Identify various soil conditions, foundation types and foundation selection criteria used in transmission structure design
  8. Discuss in detail design of drilled concrete piers, performance criteria, detailing and software for lateral load analysis
  9. Describe direct embedment design, guy anchor design, mat footings and unconventional foundations
