The strategy on repair and reinforcement on steel crane girder structures in service based on fatigue dynamic reliability is analyzed in the paper . considering the benefits of repair and the long - term economic affection after repair and reinforcement , using the fatigue dynamic reliability as constraint condition , thinking of that the sum of benefits of repair and reinforcement as object function , the optimization model is put forward . then it is used to an certain crane arc ends repair an reinforcement
5 、基于疲劳动态可靠性，对在役钢结构吊车梁的维修加固策略进行了探讨，考虑维修加固效益和维修加固后的经济影响，提出了以疲劳动态可靠性为约束，以维修加固总效益为目标函数的优化决策模式，并通过某钢厂圆弧端吊车梁的维修加固实例验证，可为工业建筑吊车梁的设计，管理和维护提供依据。
