钢吊车梁疲劳损伤与可靠性评估

Assessment of fatigue damage and reliability on steel cranegirder

通过对在役钢吊车梁疲劳损伤的调查研究，本文提出了一种钢吊车梁的疲劳损伤评估模型，探讨了损伤度与可靠度的关系，为钢吊车梁可靠性评定提出了一种简便易行的方法．

By investigating and researching into the fatigue damage on the service steel cranegirder,the paper presents the assessment model about fatigue damage of steel cranegirder.The relation between damage grade and reliability grade is discussed,and a sort of simple mothed is put forward for the reliability assessment of steel cranegirder.
