ON THE SIMPLIFIED DESIGN METHOD FOR INTERMEDIATE DIAPHRAGMS IN STEEL BOX GIRDER BRIDGES

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 speacing 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 procedures that account for estimating diaphragm spacing and stiffness that are required to limit not only distortional stresses but also cross-sectional deformation.
