Box Culvert Design Calculations Pdf Fix

For monolithic box culverts, negative moments at the corners are often overestimated.
Fix: Apply 20% redistribution of negative moments to positive spans, provided the section is under-reinforced (ρ ≤ 0.75 ρ_balanced).

PDFs frequently calculate shear at the face of the wall but ignore the increased depth at the haunch.
Fix: Recalculate critical shear at distance “d” from the face of support, considering haunch depth (typically 1.5× slab thickness). box culvert design calculations pdf fix
