To accurately investigate the distortional effect of single box double-cell box girders (SBDBG) under vertical eccentric load, the concepts of antisymmetrical and positive-symmetrical distortion were introduced, and the distortional assumption of rectangular cross section of SBDBG was supplemented. The antisymmetrical and positive-symmetrical distortion of SBDBG were described by different definitions of distortional angles. The distortion of SBDBG was researched by plate element analysis and energy variation methods. Two parameters were used to describe the distribution of stress on top, bottom, and web plates respectively to adapt to the positive-symmetrical distortion. The influence of positive-symmetrical distortion on SBDBG was considered, compared difference of distortion effect between single-cell and double-cell box girder, discussed variation of distortional angle along the length of SBDBG with the change of mid-web thickness. The results show that the analytical solution of SBDBG distortion is more consistent with the finite element solution when considering the influence of positive-symmetrical distortion, the error is less than 8.71%. The normal stress of positive-symmetrical distortion is small, and the maximum is only 28.08% of the antisymmetrical distortion. The mid-web can effectively reduce distortion effect caused by eccentric vertical load, and make the distortion normal stress decrease to 49.09% of the single-cell box girder. The distribution of the distortional normal stress on each plate is more reasonable when using two parameters to describe the positive-symmetrical distortion. The change of the mid-web thickness can make the SBDBG distortion alter obviously, and distortion will gradually decrease when the thickness increases.
