OK, engineers. I need a structural analysis of our temporary bridge. Or at least a point in the right direction for load tables for 5" x 3" x 0.2" wall welded steel tube.
I will add more strength if needed. There are some serious I-beams also available if we need them and some trusses for the sides. Basic parameters are 19 foot span and two beams per wheel track, so 4 in total.. My father thinks they will be fine but I'm not as "seat of the pants" as he is.
I can take some pictures if needed.
