Abstract: Referring to the existing evaluation methods,a fuzzy comprehensive evaluation method was applied in the evaluation of the security grade of the fatigue crack of steel box girder. According to the structural characteristics of the steel box girder,corresponding factors set and appraisal set were determined,and then mathematical model was established. Therefore, the weighting of each evaluation index is determined and corresponding evaluation standards were also classified. According to the proposed standard,the evaluation of the security grade of fatigue crack of steel box girder can be performed.

Key words: steel box girder, fatigue crack, fuzzy comprehensive evaluation

摘要: 参考现有评价方法,将模糊综合评价法应用在钢箱梁疲劳裂纹安全性等级评价上。根据钢箱梁的结构特点, 确定相应的因素集和评价集,建立数学模型,确定各评价指标的权重,并划分了相应的评价等级标准。根据此标准 可对钢箱梁疲劳裂纹的安全性等级作出评价。
