dc.description.abstract | The study investigated the analysis of three-dimensional steel bridge pavement that contained a transverse top-down crack and the three-dimensional steel bridge pavement, which used a multi-scale analysis method. Due to the long-span bridges, it easily caused the mesh too dense to be analyzed. Therefore, the multi-scale analysis method can make the long-span bridges accurately analyzed. The approach to calculate the stress intensity factor has been evaluated by using contour integrals.
First of all, the literature relevant to the steel bridge pavement had been verified to ensure the reliability of the modeling. Secondly, using the multi-scale analysis method for steel bridge pavement, and observe the number of multi-scale models required. Thirdly, when we obtain the number of multi-scale models, use this result and observe the mesh distance that influences the analysis results. Lastly, according to the result from the second point, three-dimensional steel bridge pavement’s problem that contained a transverse top-down crack, by using a multi-scale analysis method and observe the mesh distant that influence the analysis results. | en_US |
