Structural Reliability of Electric Transmission Lines - Is it a Problem?

Anthony M. DiGioia, Jr. 
GAI Consultants, Inc.

Abstract
Do electric transmission lines in the United States and around the world experience structural failures? What are the potential causes of failures? Are the risks and associated costs of failures significant? Can the risk and associated costs be quantified? These questions will be discussed at the meeting. Current transmission line structural reliability design criteria will be discussed and examples of structural failures from around the world will be presented. Finally, an open discussion will be held concerning the future role that CMU could play in resolving this issue.
