One Dimensional Finite Element Method for Continuous Curved Box Girder Including the Shear Lag Effect

Abstract:

The homogeneous solutions of the governing differential equations derived from energy variational method was used as the displacement patterns of finite segment. The stiffness and load matrix are obtained in terms of directed stiffness method and working energy principle. A one dimensional finite element method is presented to calculate the shear lag effects with multi-span continuous curved in engineering for general box girder. In addition, the tests of perspex modeled bridge and numerical calculation of the model tests by proposed method and finite element method are made. The results of model tests and numerical calculation verify perfectly in this paper.
