Fatigue Reliability Evaluation of Existing Riveted Steel Bridges
Based on the fatigue failure mechanism of riveted members, a riveted member probabilistic fatigue failure model (RMPFFM) for existing steel bridges was proposed, and a fracture finite element program was developed to calculate the geometry function of RMPFFM. Furthermore, a system fatigue reliability model of riveted bridges was proposed, and based on Monte-Carlo method, a large fatigue reliability analysis program was developed to calculate the fatigue failure probability of the whole structure. Then the system evaluation model was used to predicate the system fatigue reliability of Zhejiang Road Bridge. According to evaluation results, the probabilistic remaining fatigue life, safe inspection intervals and maintenance strategy are determined, which can control and avoid fatigue failure accident in the remaining service life.
