A box culvert is a type of structure used to convey water or other fluids under roads, railways, or other obstacles. The design of a box culvert involves calculating the structural integrity of the culvert to ensure it can withstand various loads, including soil and traffic loads. This guide provides a step-by-step approach to designing a box culvert using Eurocode 2021.
