A truss that, in one embodiment, includes alternating metal webs in non-critical portions of the truss is described. The truss includes two chords vertically spaced apart and parallel to each other, and a plurality of metal web members extending between the two chords and coupled to the vertical surfaces of the chords. The truss also includes at least two critical portions and at least one non-critical portion. The critical portions of the truss are configured so that the metal webs coupled to each side of the truss are aligned, and each metal web coupled to one side of the truss has a corresponding metal web coupled to the other side of the truss. The non-critical portions of the truss are configured so that the metal webs coupled to one side of the truss do not have a corresponding aligned metal web coupled to the opposite side of the truss. Rather, the metal webs are coupled to the chords in an alternating pattern where there is a metal web coupled to one side of the truss, then a space, then another metal web, and so on. The other side of the truss has a similar configuration, only offset, so that the spaces on each side of the truss align with a metal web on the opposite side of the truss.
