Notes: Flange Plate Reinforcement: B_p - nearly the flat width of the chord face, L_p - length of reinforcement plate L_p >= 1.5 [ h₁/sin(j₁) + g + h₂/sin(j₂) ] Weld throat size >= wall thickness of the adjacent web members Recheck chord face plastification by replacing t₀ with t_p Drill a small hole in the stiffening plate under a web member to allow entrapped air to escape prior to closing the weld. This will prevent the expanding heated air from causing voids in the closing weld Side Plate Reinforcement: B_p - at least the height of the chord, L_p - length of reinforcement plate L_p >= 1.5 [ h₁/sin(j₁) + g + h₂/sin(j₂) ] Recheck side wall shear failure by calculating A_v with t₀+t_p for t₀
