Dynamic Impact Load Effect on Suspension Crossing Frame at Transmission Tower

With the increasing number of UHV transmission lines crossing projects, suspension type spans are widely used in cross-construction. Among them, under the condition of construction accidents, the dynamic impact of the bearing cables and towers on the wires has received extensive attention. Based on this problem, this paper studies the impact of dynamic impact loads on transmission towers under construction accident conditions, and proposes reinforcement measures for transmission towers.
