A Bolted Moment Connection Model for Precast Column-Beam Joint
Bibliographic record
Abstract
In this study, bolted moment connection model for precast reinforced concrete column-beam joint was developed and tested experimentally in order to obtain and compare its bearing capacity with traditional cast-in-place monolithic joint. With this purpose, a bolted moment connection behaving like a monolithic connection were designed. A full-scale T-shape beam and column were produced separately and assembled by using high strength bolts. This specimen was tested under constant axial load on column and quasi-static reverse cyclic lateral loading on beam end. Identically same monolithic specimen was also tested under the same conditions. Test results showed that bearing capacity of bolted specimen is approximately 20% higher than the capacity of monolithic one. In addition, it is observed that the shear and moment capacity of bolted joint has increased. Hence it is obtained that it is possible to build moment resisting frame structures by using the bolted moment connection suggested within this study and this system can be used for structures in seismic regions.

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.
