| Abstract: | The article uses the finite element software ABAQUS to carry out the static analysis on the integral model of box beam for Kaiqi Bridge on Tianjin Xiangluowan River.Four a,b,c,and d models are set up on the nodes of the pivot separately by the different cell types and the different net dimensions,and the line elasticity analysis is implemented for the sub-model.The article compares and analyzes the analyzed results with the analyzed results of the overall model,and discusses the influence of the net dimension and the cell type on the analysis of numerical value simulation. |
