Shear Lag Effect of Continuous Curved Box Girder with Different Types of Support

  • Based on the homogeneous solutions of equilibrium differential equations for shear lag as the displacement patterns of finite segment,a finite segment model taking bending,torsion and shear lag into consideration was established.A corresponding program was designed to calculate the shear lag of continuous curved box girders.The shear lag of a two-span continuous curved box girder was investigated experimentally.The numerical result based on the finite segment model accords with the model test and FEM(finite element method) numerical results.An actual example was given to investigate the shear lag effects of a continuous curved box girder respectively under concentrated load and uniformly-distributed load.The research results show that the type of supports and the form of loads have an obvious influence on the shear lag effect of a continuous curved box girder.
