摘要：
Bolt slippage has significant influences on the mechanical behavior of transmission towers. In this paper, an improved finite element model named as Slip Beam model was established considering bolt slippage and load eccentricity. Traditional models including Rigid and Beam-Truss models were also studied based on ANSYS. Dynamic characteristics of three models were calculated and compared. It is found that the simulation results of the slip model agree well with the test data in contrast with the other two models. To investigate the effects of bolt slip on the dynamic characteristic of transmission tower-line systems, tower-line coupling systems corresponding to the single tower models were developed for the first time. Some valuable conclusions are presented.
