The weight of fluid passing through the culvert during maximum flow conditions. 4. Traffic Load Dispersion Methodology Ultimate Guide to Box Culvert Design Calculations via

For a 3 m span × 2 m height culvert with 1.2 m earth cover (γ_soil=18 kN/m³), LM1 traffic (UDL=9 kN/m² + TS=400 kN/axle reduced by deep cover factor α=0.8). Traffic Load Dispersion Methodology For a 3 m

spread depending on National Annex specifications) down to the top slab level.

All potential actions on the culvert must be identified and quantified.

Before initiating calculations, engineers must define clear geometrical boundaries and material classifications. Structural Geometry : Clear width ( Bintcap B sub i n t end-sub ) and clear height ( Hintcap H sub i n t end-sub ) determined by hydraulic or clearance requirements. Wall/Slab Thicknesses : Top slab ( ), bottom slab ( ), and side walls ( ). Initial sizing often estimates thickness as of the clear span to control deflections and shear stress. Haunches : Optional triangular corner fillets (
