Abstract
In this research, the seismic response of an existing bridge bent built in the 1960's in the Montreal area is studied in order to determine its seismic deficiencies. Bridges built in the 1960's were designed with outdated codes which had inadequate seismic design detailing provisions and therefore, are expected to behave poorly during an earthquake. The existing bridge bent examined has three major design deficiencies such as large spacing of ties in the column, total lack of shear reinforcement in the beam, and lack of shear reinforcement in the beam-column joint. A one-half scale model of the existing bridge bent was designed and constructed in the laboratory. This model was tested under reversed cyclic loading to determine the maximum applied load and failure mechanisms. The experimental results of the specimen are then compared to the response predictions. Both the experimental and predicted results revealed that the bridge bent is vulnerable to shear failure in the cap beams and hence, has inadequate performance. Research should be continued on the damaged specimen to determine the repair and retrofit techniques.

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.
