Ensure that your load combinations reflect (maximum gravity and lateral loads) and Service I (deflection and crack width checks). By systematically correcting the load distribution widths, transitioning to a rigid frame model, and upgrading the crack control formulas to current specifications, your modified calculation sheet will pass regulatory engineering reviews.
If you are using automated design files (such as custom Excel workbooks or specialized FEA programs) and experiencing bugs or calculation failures, check the following software settings: box culvert design calculations pdf fix
