    The effect analysis of strain rate on power transmission tower-line system under seismic excitation is studied in this paper. A threedimensional\nfinite element model of a transmission tower-line system is created based on a real project. Using theoretical analysis\nand numerical simulation, incremental dynamic analysis of the power transmission tower-line system is conducted to investigate\nthe effect of strain rate on the nonlinear responses of the transmission tower and line.The results show that the effect of strain rate\non the transmission tower generally decreases the maximum top displacements, but it would increase the maximum base shear\nforces, and thus it is necessary to consider the effect of strain rate on the seismic analysis of the transmission tower. The effect\nof strain rate could be ignored for the seismic analysis of the conductors and ground lines, but the responses of the ground lines\nconsidering strain rate effect are larger than those of the conductors.The results could provide a reference for the seismic design of\nthe transmission tower-line system.
