ABSTRACT
Box girder bridges are very popular for highways because of their high torsional rigidity and good appearance. However, the structural analysis of box girder bridges is a very difficult undertaking because of their complex deformation pattern and stress distribution, especially if the structure is continuous over intermediate supports and includes unsupported stiffening diaphragms. Although both the finite strip method and finite element method can be employed to analyze such bridges, the analysis cost is greater for the latter. In this chapter, the implementation of the finite strip procedure coupled with the flexibility approach is presented as an economical solution for the analysis of box girder bridges.
