Just as the title of the thread suggests. I've always used Fig 29.5-3 since I figured that a "trussed tower" sounded more appropriate for a box truss. However, I suppose "lattice framework" sounds similar too (Fig 29.5-2), plus it gives lower Cf values. Unfortunately, ASCE doesn't give much of an explanation of the intent of these figures, so I'm in debate. I'm just looking for what is most appropriate......any opinions?
