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

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
