Fatigue Properties Estimates of Orthotropic Deck on Steel Bridges

Abstract:

For estimating the fatigue properties of orthotropic deck bridges, a finite element analysis method was provided. In the method, the models of orthotropic decks steel bridge were established by using Midas and Ansys finite element software respectively, the Midas software has tracked two kinds of live load positions that corresponding to maximum and minimum stress of the fatigue checking points, and the most unfavorable loads were loaded to the Ansys model, then the stress ranges of fatigue checking points were obtained and the fatigue properties of the bridge were estimated. The results show that, it is feasible that using the new finite element method to checking the fatigue performance of orthotropic deck steel bridge.
