Abstract: In view of the problems existing in the transmission tower-wire dynamic response analysis under seismic action, the seismic wave simulation analysis was carried out by ANSYS finite element software. Considering the influence between seismic traveling wave effect and the tower-wire, three-tower two-wire coupled system suffered multi-point incentive under typical earthquake was analyzed, the results show that the displacement and the peak acceleration value of the system is larger than that suffered the consistent incentive, and the response is more obvious along the tower height direction. So the earthquake resistant design for the transmission tower-wire coupled system should be paid enough attention.

Keywords: tower-wire coupled system; seismic response; traveling wave effect; multi-point incenive
