For spans larger than 8 feet, many standards like the MnDOT LRFD Manual require a minimum top slab thickness of 9 inches and a bottom slab thickness of 10 inches. 2. Loading Analysis
Before beginning calculations, engineers must establish the material properties and geometric constraints. Typical concrete compressive strength (
) is commonly 60 ksi for rebar or 65 ksi for welded wire fabric.
Box culverts are subjected to complex loading conditions that vary with the depth of the earth fill.
