Nonlinear Time‐History Analysis of a Six‐Story Wood Platform Frame Buildings in Vancouver, British Columbia
Bibliographic record
Abstract
In 2009, the British Columbia Building Code was amended to increase the allowable height of wood‐frame residential buildings to six stories from four stories. This paper presents the details of a numerical study undertaken to understand the seismic performance of six‐story wood‐frame buildings designed in accordance with the 2006 British Columbia Building Code. To investigate the seismic behavior, a four‐story building was used to represent the benchmark seismic performance prior to the amendment. Two independent analyses using computer programs DRAIN‐3DX and SAPWood were carried out on representative buildings located in the city of Vancouver, BC, using a suite of 20 earthquake records scaled to the design seismic hazard level for the site. The analyses showed that six‐story wood‐frame buildings had similar performance to four‐story wood‐frame buildings.

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.
