A new design method for stiffened compression flanges of box girders
Abstract A new method for the design of stiffened compression flanges of large steel box girder bridges is presented. It is based, like that presented 10 years ago by Maquoi and Massonet, on the orthotropic plate approach, but the mathematical formulation and its use are more simple. In addition, it allows for account to be taken of a non-uniform stress distribution in the flange and thus enables the analysis of the shear lag effects on the plate buckling. The physical differences between plate buckling under uniform and non-uniform compression, respectively, are clearly shown. Finally it is found that the collapse ultimate state is little influenced by shear lag.
