| Abstract: | Under the existing theoretical and experimental basis of the composite structure, by intro- ducing the shear lag warping displacement function of steel-concrete composite box girder flange plate, this paper derives a curvature formula of Composite Box which considers the role of shear lag effect and explores the shear lag effect of the deformation of the beam. The correction method of the compos- ite box girder shear lag factor with the shear lag coefficient is proposed and proved here. It can improve the relevant theoretical system about rigidity design of composite beam. |
