    Abstract

    The design of steel box girder bridges under unsymmetrically placed live loads involves consideration of intermediate diaphragms that are required to limit cross-sectional deformation and distortional normal stresses. In this paper, the required spacing and stiffness of such intermediate diaphragms are examined by performing a parametric study based on Beam Analogy. The results of the present parametric study yield a series of simplified design procedure that accounts for estimating diaphragm spacing and stiffness that are required to limit not only distortional stresses but also cross-sectional deformation.
