Abstract：Based on the engineering practice, with linear elastic scale theory and the secondary scale design method, scale model design of transmission tower-line system is completed including two towers and three spans lines. Considering the characteristics of near fault seismic velocity pulses and the randomness of earthquakes, the shaking table experiments are performed using three near-fault seismic waves. By introducing the displacement response ratio of different incident angles, the influence of incident angle on the dynamic responses of tower-line system is investigated. The results show that the incidence angle has great influence on the dynamic response of transmission tower-line system, the most unfavorable incident angles of the transmission tower-line system is different for different seismic wave, and the amplification degree of the transverse displacement response of the tangent tower is far greater than that of the longitudinal displacement response under the excitation of different incident angles. Therefore, the influence of the incident angle of the near-fault seismic wave should be considered for the dynamic response of the tower-line system. The test results can be used as an important reference for seismic design of large span transmission tower-line system.
