We're designing a bridge per the LRFD specifications. Our DOT requires access openings in the bottom flange spaced at not more than 300 feet. For our 3-span bridge this requires openings in the second span. LRFD says to place these in low stress regions. Clearly, anywhere in the second span...
LRFD has criteria for the effective slab width for a conventional cast-in-place deck on steel girders. Has anyone designed a plate girder using an exodermic deck? If so, what did you do for your transformed section?
