Box Culvert Design Calculations Eurocode 2021 -
Often, the concrete class chosen is ≥ C30/37 or C35/45 to meet exposure classes (e.g., XC4, XD2, XD3 for soil/water contact).
For a slab section (d = thickness – cover – φ/2, cover=35–50 mm):
– Provides rules for the ultimate limit state (ULS) and serviceability limit state (SLS) verification of the concrete elements. Part 1-1 covers general rules, and Part 2 focuses on concrete bridges/culverts.
Under the characteristic combination of actions, compressive stress in the concrete must be limited to prevent longitudinal cracks:
