Monolithic SMA-reinforced double slotted beam-column connection
Bibliographic record
Abstract
Abstract Reinforcing concrete connections using superelastic shape memory alloy (SMA) facilitates developing monolithic self-centering earthquake-resistant concrete frames designed to dissipate energy through a flag-shaped hysteretic response. In this research, a new monolithic self-centering concrete beam-column connection was proposed and experimentally validated by testing a large-scale connection under cyclic loading. The connection was detailed to precisely control the center of rotation in the beam member and mitigate damage to slabs attached to the concrete beam. The connection was designed to relocate the center of rotation away from the face of the column based on the newly developed double slotted beam (DSB) technology. The test results were compared with experimental tests of SMA-reinforced single slotted beam-column connection found elsewhere in literature and a control conventional reinforced concrete connection. Test results indicated the ability of the connection to self-center while experiencing a flag-shaped hysteretic response.

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.
