Abstract:The friction forces between connecting plates are not taken into account in the shear capacity calculation of high-strength bolted bearing-type joints in the current Codes, which is not consistent with the bearing mechanism of high strength bolts.The principle of virtual work was adopted to go through pre-stress simulation method, and the finite element method was adopted to analyze the loading process of bearing-type joints.The results show that, without considering the friction forces between connecting plates, when the bearing capacity of connection is controlled by bolt strength, the shear capacity of high-strength bolted bearing-type joints will be underestimated.In this paper, based on numerical simulation, a reasonable method considering friction forces between connecting plates was proposed to calculate shear capacity of high-strength bolted bearing-type joints.Compared with FEM results, the error of new method is less than 10%.
