If you could give us a drawing of the bridge it would be helpful. However, I would think that you should write a bunch of equations to get the same stresses as the full scale bridge. This should involve tensile, compressive and shear stresses in the truss sections ,F/crossection area, and bending moment streses of the form wl^2*c/I w=uniform load and Fl*c/I for point loads Deflections would be of the form wl^4/EI and Fl^3/EI DISCAIMER: I am no expert on this. Just my gut feel.

Thank you Zekeman I had this suspect; anyway I will post a drawing of this bridge a soon as I complete the final sketch, but statically it is comparable to a simple beam with two support.
