Abstract
A single-storey precast concrete structure constructed in 1963 with masonry-infilled walls was selected for a seismic evaluation. The structure is located in the Montreal region, and is considered a post-disaster emergency building since it houses spare parts for municipal facilities. The warehouse was first evaluated through a visual inspection and identified as being seismically vulnerable. A series of three-dimensional models of the structure were analyzed to evaluate the seismic performance of the structure with respect to the seismic design requirements of the 1995 and 1965 edition of National Building Code of Canada (NBCC). The structural models were analyzed using a linear static analysis accounting for the effects of different diaphragm configurations on the lateral load resisting columns and the effects of masonry-infilled walls. The seismic analyses showed that the warehouse does not satisfy either of the NBCC 1995 and NBCC 1965 requirements. A seismic rehabilitation scheme is proposed comprising the addition of reinforced concrete shear walls, steel braces and an upgraded roof diaphragm. The proposed retrofit satisfies the seismic design requirements of NBCC 1995. Finally, the proposed seismic design provisions of NBCC 2005 are briefly summarized and the impact of the new seismic design provisions on the retrofitted structure is discussed.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
