Taking Wei River Bridge with span combination of 69m+7×90m for example, the method of determining the steel-concrete joint section for variable cross-section steel-concrete hybrid continuous box girder bridge were investigated by finite element and parameter sensitivity analysis. The results show that it was an effective method for hybrid girder highway beam bridge from the view of mechanical property that the bending moment under dead load combination was employed as the main parameters, considering the negative bending moment in the pier top and the amplitude of bending moment in the joint section under live load. But based on reasonable structure stress conditions, the length of steel box girder that the host material of the bridge was concrete could determined by economy principle. |
