Effective length factors for solid round chord members of guyed towers.

Chord members of twenty-five all-welded guyed-latticed communication steel tower sections were tested in the Structural Engineering Laboratory of the University of Windsor to determine the effective length factors of the chord members. Two different manufacturers, viz., Pirod Inc., Plymouth, Indiana, and ERI Inc., Chandler, Indiana, provided the test specimens. All tower sections were fabricated from solid round members and were triangular in cross section. Tower sections provided by ERI were 4.57 m (15.0 ft.) long with continuous diagonal bracings welded to the chord members, while those provided by Pirod were 6.09 m (20.0 ft.) long with the diagonal bracings cut and welded to the chord members. The diameters of the chord members varied from 38.1 mm (1.5 in.) to 69.85 mm (2.75 in.) while the diameters of the diagonal bracings varied from 12.7 mm (0.5 in.) to 22.3 mm (0.875 in.). The tower sections were tested in a horizontal position. One chord member of the tower was cut and tested by applying a load at its center while the diagonal bracings remained attached to the chord members. The stiffness contribution of diagonal bracings to the ends of the chord members was also computed numerically. (Abstract shortened by UMI.)Dept. of Civil and Environmental Engineering.
