![]() However, all these cases are dealt separately and a significant amount of time is used to come up with the final design. In India, many designers use STAAD.Pro for the structural analysis of box culverts and bring the results of this analysis to a Microsoft Excel spreadsheet to carry out the remaining calculations. Microsoft Excel spreadsheet is therefore often used to speed up this repetitive calculation process. In practice, engineers are following exactly the same process with different dimensions and loading conditions to design box culverts. The design process of box culverts is relatively easy and repetitive because of their typical geometric configuration. ![]() In some cases, non-standard box culverts are also used, for which the design document has to be produced per project design specification. Because of their simple geometric configuration, precast concrete box culverts with various dimensions are commonly used in the U.S. Box culverts are structurally rigid, easy to construct, and easy to add length when needed. ![]() One of the fast and economical ways of putting tunnels or stream crossings under roadways is to use box culverts. ![]()
