Abstract

The performance of high-strength bolt corrosion fatigue related to the safety of structure. It is generally thought that high-strength bolt crack size and the critical crack size conform to logarithmic normal distribution. If the probability density functions of crack size and the critical crack size interfered, high-strength bolt maybe destroyed. Based on the fracture mechanics theory, according to the Gerberich-Chen formula, the corrosion fracture growth threshold value of high-strength bolt was estimated. According to fracture mechanics method, based on reliability theory, the high-strength bolt corrosion fatigue reliability model was deduced. And high-strength bolt corrosion fatigue reliability was analyzed. It was easy and convenient that analysis high-strength bolt joint corrosion fatigue reliability by this model. Hence the high-strength bolt joint corrosion fatigue can be predicted. This method may provide the reference for the high-strength bolt joint fatigue analysis.
