THE CONDITION OF WARPING CONTINUITY OF THIN-WALLED BOX-GIRDER$
|
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.
