Paper Title:
Fatigue Performance of Deck Slab under Hogging Moment in Continuous Composite Girder Bridge
  Abstract

Based on the vehicle load model for fatigue design, the stress influence line of the reinforcement in the concrete slab of northern approach of Jiubao bridge, a multi-span continous composite bridge, under the global live load was obtained by spatial frame structure finite element model, while the stress history of the reinforcement under the local live load was obtained by the spatial refined finite element model. Then the stress spectrums under global and local live load were obtained by Rain-flow method according to the predicted traffic volume in the future 100 years and comparisons of amplitudes of equivalent stress under different loads were achieved. At last the fatigue lives of the slab under the different loads were calculated and compared either.
