Title: A Numerical Assessment of Cross-Sectional Forces in the Joints of Multi-Beam Box Girder Bridges
Abstract: This work investigated the need to apply post-tension strands in transverse direction of multibeam box girder bridges. It also highlighted the capability of Finite Element Method (FEM) to evaluate the current design procedures, model the construction stages, and study the need of nonlinear analysis in certain cases. In this paper, 3D finite element model have been developed to analyze the cross-sectional forces in the joints of multi-beam box girder bridges. The current design method is based on linear analysis. A model based on shell elements is used in linear and nonlinear analyses including two analysis phases. The analysis phases simulate the construction phases of multi-box girder bridge. For straight bridges current design methods based on orthotropic plate models give reasonable results compared to the results of the advanced model. For bridges with a skew or curved geometry plan orthotropic plate models give poor predictions for the forces and moments in the joints.
