Impact of changes in the NBCC 2005 seismic provisions on the design of restraints for OFCs and essential rigid components
Bibliographic record
Abstract
The seismic design provisions in the NBCC 2005 are based on an earthquake hazard level higher than \nthat used for the NBCC 1995 provisions, which involves an increase in the seismic design accelerations. \nThis paper presents the main results of a study of the impact of the increase in accelerations on the \nseismic design of rigid non-structural components such as transformer tanks, reservoirs, emergency \npower generators, etc., and their foundations or restraints. The provisions of the 1995 and 2005 editions of \nNBCC for equipment located above grade level and for the calculation of base shear forces of low-rise \nbuildings or control units for essential equipment having different lateral load resisting systems of limited \nductility are presented as well. In order to get a global conclusion about the behaviour of rigid components, \nthe analysis has been made in relation with different earthquake records.

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.
