Lateral behavior of full-scale concrete-filled carbon composite columns
Bibliographic record
Abstract
Full scale concrete-filled carbon composite columns without longitudinal and transverse reinforcing steels are tested to investigate the lateral behavior of columns confined with carbon composite tubes. In the present study, the full-scale circular and square concrete-filled carbon composite tubes (CFCTs) with various winding angles with respect to longitudinal axes of the tubes are subjected to lateral loads under a constant axial load. The influence of thickness and winding angle of carbon tubes on the lateral behavior of concrete columns is studied both experimentally and analytically, demonstrating that the calculated ultimate moment capacity of confined columns compares well with test data. For this analytical process, stress–strain relationships of confined concrete columns uncovered by the authors are used to identify the distribution of confined compressive concrete strength at failure. This stress–strain model considers the influence of winding orientation of carbon fibers on the confining capability of the concrete core.Key words: carbon composite, lateral capacity of confined column, strength, filament winding.

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.
