Seismic responses of a long-span transmission tower and tower-line system
Journal of Physics: Conference Series, 2022 The seismic responses of a long-span transmission tower (LTT) and tower-line system (TL) are presented in the paper. The mode decomposition response spectrum method (MDR) and time domain analysis method (TD) are both employed to obtain the seismic responses.
