Abstract
The existing research on the reinforcement of transmission lines focuses on the main materials and foundations. To address the key issue of reinforcing the connection nodes between the upper structure and foundation of transmission line towers, a finite element model of this node was established using Abaqus, considering different stress conditions under natural disasters. Comparisons with the calculation results of both original and current specifications revealed that after reinforcing the upper structure, the weakest point is the shear failure of the connecting bolts between the shoe plate and the main material of the node, necessitating an increase in overall load-bearing capacity. Therefore, a node reinforcement plan compatible with the reinforcement type of the upper structure main material was proposed, which allows for construction without power outage and was verified through true type tests. This research on node reinforcement contributes to improving the service value of transmission lines and provides new insights for the reinforcement of similar prefabricated building nodes.
