| Abstract: | On the basis of the theory of thin-walled member, the
continuity of warping in analysis of bending shearing flow and warping
shearing flow in thin-walled box-girder is studied. With the continuity
condition of warping, the formula of warping shearing flow in restrained torsion of
thin-walled box-girder is established. The error in relevent references
is pointed out and corrected. The warping shearing flow in a cantilever
box girder under restrained torsion is calculated. |

| Keywords: | thin-walled box-girder restrained torsion warping deformation shearing flow |
