Based on the numerical results of model test, the distribution of transverse stress in flanges of curved box beam is presented in this paper. By using finite element method (ANSYS software), the variation of transverse stress along the flanges of box beam versus radius is given. For two-cell curved continuous box beams the utility calculating formulas about the ratio of transverse stress to normal stress in flanges are presented, which can provide references for actual structural design.
