A finite element simulation model of bolted joints connecting single shear plane and double shear plane is established for the joints of the tower Leg joint of the transmission tower. The hysteresis curve of the joint is obtained by applying the low cycle load. The skeleton curve analysis, energy dissipation analysis and stiffness degradation analysis are carried out. The energy dissipation and mechanical properties of the transmission tower bolt joints under low cycle loading are studied. The results show that the joint flexibility of single shear connection and double shear connection The deformation process is basically the same. After that, the two nodes all have slip phenomenon. The double-shear joints experience two slip processes. During the bolt slip process, the node has the strongest energy consumption. The double-shear joints have stronger ultimate bearing capacity and stiffness. Keep features better and consume more energy.
