Abstract:On the designing of transmission tower redundant members, there is significant difference in the specification requirement.   The relevant provisions of the codes of China, American, Europe and India were sorted out, the results were compared and analyzed with test data of Actual engineering tower and the finite element numerical simulation analysis data. A new formula for design of transmission tower redundant member was obtained, which have been proved meet the requirement of engineering and can be taken as reference to the related standard revision.

Keywords:transmission tower; redundant member; prototype test; slenderness ratio; bracing force
