Advances in transmission line analysis tools allow the designer the ability to better define structural performance of transmission line towers. These advanced tools can be used to determine a transmission tower failure mechanism and member loads. These computer programs attempt to model non-linear behavior, post-buckling performance, and capacity variation of the transmission tower structural system. The capabilities presented in this paper can be used for both production and research applications. These advanced programs have been used to investigate tower failures, evaluate discrepancies between graphical solutions and elastic analyses, perform probabilistic studies of design parameters, and as an alternative option to Mi-scale testing.
