Shear in Gusset Plate (Truss Bridge Guide Specs. 1.11 and AISC 13th Edition J4.2)
         VDL = shear force due to DL acting on the section                                                                         Bridge Number                   6748
         VLL+I = shear force due to LL+I acting on the section
         Vped LL = shear force due to pedestrian live load acting on the section                                                   designates input field
         Fy = minimum yield strength of gusset plate material
         Fu = minimum tensile strength of gusset plate material
         tg = thickness of gusset plate before section loss
         wg = width of the gusset plate at the cut section
         Loss = percentage of section loss in gusset plates
         Ag = gross area of 2 gusset plates including section loss
         Nrivets = number of rivets/bolts crossed by whitmore effective width
         Anet = net area of 2 gusset plates including section loss
         fVny = shear yield capacity at cut section = fvy∙(0.74∙Fy/√3)∙Ag, where fvy = 1.00 (per Truss Bridge Guide Specs 1.11)
         fVnu = shear rupture capacity at cut section = fvu∙(0.60∙Fu)∙An, where fvu = 0.75 (per AISC13th Edition J4.2)
         fVn = smaller of fVny and fVnu
         RFinv = (fVn - 1.3∙VDL - 2.17∙Vped LL) / (2.17∙VLL+I)
         RFop = (fVn - 1.3∙VDL - 1.3∙Vped LL) / (1.3∙VLL+I)
             diariv =   0.875     in           (diameter of rivet/bolt)
