Abstract: The transmission line-tower coupled system is analyzed using SAP2000. When transmission line tower coupled system is subjected to spatially varying ground motion, it may face higher forces and stresses than they were designed to withstand. It is sensible to expect that the transmission line-tower systems are unsafe from earthquake motion so a proper analysis is required. There are a few cases in past of harm to electrical cables during the earthquakes. A few troubles may emerge during the dynamic investigation of transmission line-tower framework as the framework as a whole is non-linear in nature. Like bridges this system is also a type of extended structure and soil conditions may change with the distance covered. A ground motion with phase difference or spatially correlated ground motion may be used to excite the system. Transmission towers will be modeled as truss elements and cables will be modeled as tension members in SAP 2000. After exciting the structure using spatially varying earthquake motion, the response of the system will be studied using Response Spectrum method and Time History analysis method
