New concepts are being advanced for the design of electrical transmission structures. The papers in this book cover the following: weather-element loading conditions, structural options, design recommendations, foundation alternatives, research efforts, and code requirements. Weather-element loading conditions feature reliability-based design, new wind loading criteria, and instrumentation for wind loading on an operating line. Structural options emphasize formed-plate steel poles, experience with laced towers fabricated from cold-formed shapes, and prestressed concrete poles. Design recommendations provide guidance for cold-formed shapes and bolted connections. Foundation alternatives feature test results and design recommendations. Research efforts provide current information on strain gage monitoring, full-scale tower tests, and strength distributions for reliability-based designs. National Electrical Safety Code changes are also presented. Discussion sessions on each of the featured topics are also included.
