Abstract

The stress on the key nodes of transmission towers is complex, which plays a vital role in the stress and stability of the whole structure of transmission towers. Due to the larger negative head of the link and the larger connecting plate at the K node of the curved arm of the transmission tower, the actual stress of some components is quite different from the theoretical calculation results. At the same time, the load value of the smaller part is not clear when the included Angle of the stressed material at the K node is less than 25°.In this paper, the difference between the stress of the bar at the K node of the curved arm and the ideal model is studied, and the stress status of the position with small Angle is analyzed, and the reasons for the difference and the suggested value of the position with small Angle are analyzed.
