“…Ebrahimi et al (2022) performed test study to obtained the load-deformation curves of joint under cycle loading, and then proposed a mathematical formula to describe the load-deformation curves. Lu et al (2018) Studied the influence of the cycle loading on the joint slip by tests, and the results showed that bolt-slip load decrease with the increase of the cyclic loading.…”

Introduction: The mechanical properties of joints have a significant impact on the dynamic response of transmission tower structures.Methods: Considering bolt slip, the numerical model of the transmission tower K-joint is established. The mechanical properties of K-joints are studied from three aspects: failure mode, load-displacement hysteretic curve, and stiffness degradation by numerical method. The effects of bolt preload, friction coefficient, and member strength on the hysteretic properties of the K-joint are analyzed.Results: The results show that due to the complexity of K-joints, bolt slip will lead to the reduction of ultimate bearing capacity and the change of failure position. In order to accurately obtain the mechanical properties of K-joints, the influence of bolt slip should be considered in the research process; The plumpness of load-displacement hysteretic curve is greatly affected by parameters; The stiffness of K-joints degenerates with the increase of loading times.Discussion: The results provide a reference for the mechanical analysis of the transmission tower.
