Bridge structure fatigue process is a large number of factors that influence the extremely complex phenomenon, most influence factor is essentially random. In this paper the limit state equation on the basis of analysis, numerical characteristics of random variable. Introduction of the first order two moment method, based on the curve and the Miner linear cumulative damage rule of high speed railway spatial rigid frame shear pin structure fatigue life reliability assessment.
