Flexure-torsion Analysis of Variable-curvature-box Girder Considering Non-coincidence of Torsion Center and Gravity Center[J]. Journal of Civil and Environmental Engineering, 2007, 29(3): 66-69. DOI: 10.11835/j.issn.1674-4764.2007.03.016.
In order to consider the effect of non-coincidence of torsion center and gravity center
the rectangular variable-curvature-box girder with vertical symmetrical axis is studied. Considering the influence of shear deflection and non-coincidence of torsion center and gravity center
the elastic equilibrium formulas are established. Based on deformation equations of the girder and the relations of inner forces and deformations
the flexure-torsion differential equations are developed. The equilibrium differential equations and Galerkin methods formulas for clothoid curved box girder are presented.
