Eurocode 2021 emphasizes robust corner detailing. Provide diagonal reinforcement (U-bars) at internal and external corners to resist frame action moments and prevent hinging failure – typically 2 × H16 bars per corner, anchored with standard bends.
Culverts are preferably designed to avoid shear reinforcement. The design shear force ( VEdcap V sub cap E d end-sub ) must not exceed the baseline concrete shear capacity ( VRd,ccap V sub cap R d comma c end-sub
: Concentrated tandem system and uniformly distributed loads.
Increased focus on precast modular designs, requiring calculations for lifting, handling, and joint sealing (waterproofing). Conclusion
