(V_Ed ≈ 35 kN/m from analysis): ( v_Rd,c = C_Rd,c k (100ρ_1 f_ck)^1/3 b_w d ) ρ₁ = As/(b d) = 565/(1000×204)=0.00277, k=1+(200/204)^0.5=1.99 ≤ 2.0. v_Rd,c ≈ 0.12×1.99×(100×0.00277×30)^1/3×1000×204/1000 = 42.2 kN > 35 kN → OK.
Designing a box culvert requires a multi-disciplinary approach using several Eurocode parts:
For ultimate limit state (ULS):
for structural design) follows a rigid structural report format. A standard design report for 2021-era projects includes hydraulic sizing, load determination, and structural verification. 1. Design Data & Geometry
