Box Culvert Design Calculations Eurocode 2021 -

Example: 300 kN axle, fill 0.7 m, dispersion area = (0.4 + 2×0.7) × (0.4 + 2×0.7) = 1.8 m × 1.8 m → pressure ≈ 92.5 kPa.

Check shear capacity without shear reinforcement ($V_Rd,c$). Culverts rarely have stirrups (links) in the slabs/walls due to construction complexity; shear is usually resisted by concrete alone. box culvert design calculations eurocode 2021
