IMPROVING NON-STRUCTURAL SEISMIC RESTRAINT IN CANADA
Bibliographic record
Abstract
Seismic restraint of non-structural elements in Canada is shaped by a standard called CSA-S832 published by the Canadian Standards Association, but is not formally codified. In Canada the term Operational and Functional Component (OFC) is used to describe all the components in a building that facilitate its occupancy, but are not part of the primary structural systems. This can range from facades and MEP systems, to furnishings and public art. The National Building Code of Canada provides force level calculations, general prescriptive limits on the types of restraint strategies, but there is no explicit reference to industry driven guidelines or exemptions. This has resulted in confusion, and mixed results in an industry segment that relies heavily on design by deferred submission during construction. Which can often lose sight of the primary design and performance goals of the primary project team. We will observe the differences in code mandates in the USA. The US market relies heavily on industry driven standards, such as SMACNA, which reasonably mirror the governing code for determining forces, ASCE 7. However, what remains outstanding is the understanding of risk and prioritization of restraint needs, and restraint compatibility between building systems, particularly MEP. Maintaining adequate physical gapping between mechanical and electrical systems is not clearly the responsibility of anyone when using the deferred submission delivery model. This presentation introduces the risk assessment theory embedded in CSA-S832 and outlines how its quantitative methodology can be used by a client to assess risk, quantify upgrades, and guide longer term mitigation efforts to address deficiencies that would otherwise be left unchanged through administrative provisions of the permitting process (i.e. grandfathering). Additionally, we will discuss how a more formal implementation of its methodology could be used by a project team to prioritize, coordinate, and dictate adequate restraint detailing across building systems and trade boundaries to achieve greater resilience outcomes.

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.
