Abstract:When calculating high-strength bolted bearing-type joint controlled by member strength, the consideration of friction force directly affects the carrying capacity. This process was analyzed in this paper according to the mechanism of high-strength bolted bearing-type joint, and FEM was used to simulate the loading process, in which the cooling method was used to simulate the prestress of high-strength bolt. The results have shown that, when connection capacity is controlled by member strength and the friction force is not considered for high-strength bolted bearing-type joint, the carrying capacity will be reduced. A proper calculation method based on analysis was proposed.
