摘要
将荷载过程视为随机过程 ,考虑既有混凝土梁的抗力劣化过程 ,采用时变的可靠性计算式 ,在对实验结果进行分析基础上 。
Taking the train load as random process,considering the resistance deterioration of the existing concrete beam,the time-dependent reliability formula is adopted to evaluate the reliability of concrete beam of a railway bridge without design information according to the analysizing result of test data.
