Dhengr: That's a very reasonable explanation. I hadn't taken into account that the formula compensates for the expected forces on the box girder.

Edit: I wrote the endpoint statement wrong. As strength of steel approaches infinity, my required web thickness also approaches infinity.

In CMAA 74 Paragraph 3.5.1 Proportions for Welded Box Girders, one of the equations is: h/t ≤ 1000/sqrt(σy) where, h = height of web (in) t = thickness of web (in) σy = min. yield strength (ksi) This formula does not exactly work the way one would expect. Consider this example: Let's say I...
