Twenty-six all-welded lattice tower specimens were simply supported in the horizontal position and tested under a concentrated load at midspan. Of the twenty-six specimens, eight had solid round single-braced diagonals and the remaining eighteen had solid round cross-braced diagonals. Three different types of arrangements were used for the cross-braced specimens: Type I: One diagonal is straight in-plane and the other is pre-bent out-of-plane. The two diagonals are welded at their intersection (six specimens). Type II: One diagonal is straight, in-plane, and continuous. The other diagonal is straight, in-plane, and cut and welded to the first diagonal at intersection (eight specimens). Type III: Both diagonals are pre-bent out-of-plane and welded together at intersection with welds in the plane of the face of the specimen (four specimens). Specimens with three different leg sizes (38, 44, and 51 mm solid rounds) and two different sizes of diagonals (19 and 22 mm) were used in this investigation. (Abstract shortened by UMI.)
