Under the influence of the wind loads, the prestress of guy in the guyed door type transmission tower has a great impact on the mechanical properties of its structure. In order to study this effect, The paper establishes the appropriate nonlinear finite element model of the guy-door- type transmission tower through the use of structural analysis software, analysis the mechanical properties of the tower structure under different initial stress on the condition of the most negative angle of attack, obtain the rule that the changes of initial stress of guy has an influence on the support reaction of guyed transmission tower, the maximum displacement of tower nodes and the bar axial stress, providing the available value for the design and constriction of tower structure, and ensuring transmission tower structure self-reliance, stability and well run.
