Though a transmission line has tremendously numerous modes, responses of transmission lines subjected to earthquakes can be computed by the method of modal analysis adopting only a few symmetric modes of transversal wave in low frequencies and modes longitudinal one in high frequencies. This paper presents simplified nomograms for computing natural frequencies, additional tensions and participation factors of their modes of diverse transmission lines for analyzing earthquake responses of towers and transmission lines systems.
