无设计依据的混凝土梁承载力可靠性评估
Reliability Asessment of Concrete Beam of Railway Bridge without Design Information
【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 ,对一座无设计依据的混凝土梁可靠性进行了评估
【Abstract】 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.
