Force analysis of variable cross-section continuous box girder bridge

Force analysis of variable cross-section continuous box girder bridge In order to study the distribution of stress and deformation of variable cross-section continuous box girder bridge, in this paper, the finite element method is used to establish the model of variable cross-section continuous box girder bridge. Considering the layout of lane load, the combination of working conditions is calculated, and the stress and deformation of variable cross-section continuous box girder bridge are analysed. The results show that the maximum stress of the bridge generally occurs at the continuous beam span middle section or support, and sometimes the stress value at the vehicle load point is also large. These positions with large stress values should be considered in the design of box girder. The vertical displacement of bridge is small, removing settlement of end support. The maximum vertical displacement of bridge span middle section is 15 mm, and the bridge design scheme is safe, reliable and economical. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png International Journal of Critical Infrastructures Inderscience Publishers

Abstract

In order to study the distribution of stress and deformation of variable cross-section continuous box girder bridge, in this paper, the finite element method is used to establish the model of variable cross-section continuous box girder bridge. Considering the layout of lane load, the combination of working conditions is calculated, and the stress and deformation of variable cross-section continuous box girder bridge are analysed. The results show that the maximum stress of the bridge generally occurs at the continuous beam span middle section or support, and sometimes the stress value at the vehicle load point is also large. These positions with large stress values should be considered in the design of box girder. The vertical displacement of bridge is small, removing settlement of end support. The maximum vertical displacement of bridge span middle section is 15 mm, and the bridge design scheme is safe, reliable and economical.
