Method for Estimating Bending Stiffness of Concrete Girders during Train Passage Considering Effects of Concrete Cracks and Non-structural Members

This paper presents the results of a study to investigate a method for estimating the stiffness of concrete girders when calculating the dynamic factor and deflection. Based on a fatigue test of concrete members, we proposed an estimation formula which takes into account the reduction in bending stiffness due to...
