• Geometry: Define clear span ($L$), rise ($H$), wall thickness ($t_w$), and top slab thickness ($t_s$).
• Concrete: Define strength class (e.g., $C30/37$).

  The design of reinforced concrete box culverts under current Eurocode standards involves a integrated approach using (Basis of structural design), Eurocode 1 (Actions), and Eurocode 2 (Concrete design) . While the fundamental Eurocode 2 (BS EN 1992-1-1) provides the general rules for concrete structures, specific guidance for culverts—often treated similarly to bridges—is found in BS EN 1992-2 . 1. Design Basis and Standards The design of a reinforced concrete box culvert

  • Permanent actions (unfavorable): $\gamma_G = 1.35$ (increased from 1.30 for some verification cases).
  • Variable actions (unfavorable): $\gamma_Q = 1.50$ (unchanged).
  • Soil weight (unfavorable): $\gamma_soil = 1.35$ (explicitly required).
