Abstract

In order to consider bending and torsion effect of curved box girder varying with transverse axis and longitudinal axis, a spatial finite element method considering initial curvature and variable curvature was presented. Assuming that the curvature varied linearly along transverse axis, it was obtained that the relation between bending deflection angle of arbitrary point within curved box girder and radius of curve was inverse proportion. Based on the bending and torsion theory of thin-walled box girder, stress and displacement relations of arbitrary point of variable-curvature box girder were deducted, which the curvature was regarded as the function of coordinate z. Based on the above two treatments, and regarded shape functions as interpolation functions of variable-curvature within element, isoparameter finite element of curved box girder of variable-curvature within element was established. From the theory presented above, the computer program was developed, and the results of example demonstrated the validity of the proposed methods to variable-curvature curved box girder.
