| dc.description.abstract | Multi-scale numerical modeling is common in structural monitoring and is a modeling strategy for building long-span bridge models. The key to this method is the information transfer relationship between different scale models. In finite element model, long-span bridges are too long to span, which makes it difficult to analyze the mesh after modeling. In order to analyze the problem of long-span bridges. In this study, multi-scale analysis was used to analyze the structure of 3D steel deck pavement and modeled using ABAQUS finite element analysis software.
First, the literature relevant to the steel deck had been verified to ensure the reliability of the modeling. Secondly, a simple case testing was implemented. Based on the nodal displacement to execute the multi-scale analysis and inspect the appropriateness of the testing. According to the testing result, the nodal displacement is available to be used for the information transfer between solid elements.
In the process of modeling, the mesh must be different. Therefore, to completely transfer the information of nodes of models in different sizes, FORTRAN programming language is compiled for supplementary. Interpolating the displacements of different models by taking advantage of inverse distance weighting, then applying the multi-scale analysis method on the steel deck modeling. Eventually, similar data is obtained in the stress and strain field as expected. Hence, this method can be considered to be used during building the long-span bridge model.
