is the effective angle of internal friction of the backfill soil. The horizontal pressure profile is split into: : Soil-induced horizontal pressure : is the depth from the ground surface). 3. Ultimate Limit State (ULS) Load Combinations

). The design shear resistance of a concrete member without shear reinforcement is calculated as: is the effective angle of internal friction of

Box culverts are ideally designed thick enough to avoid shear reinforcement ( Ultimate Limit State (ULS) Load Combinations Box culverts

Traffic load models must be applied to the ground surface and dispersed down to the top slab layer.

and associated loading codes, based on 2021-2024 standards and practices.

, the designer must either reduce bar spacing or increase the cross-sectional area of steel ( Ascap A sub s ), reducing the working stress ( σssigma sub s ) of the bars. 8. Summary of Geotechnical Checks (EN 1997)
