Wind Load on Ridge and Field Tiles on a Residential Building: A Full Scale Study
Bibliographic record
Abstract
This paper presents a large-scale Wall of Wind (WoW) investigation of external and underneath wind pressures on roof tiles installed on a low-rise building. The dimension of the low-rise building tested was 2.74 m (9 ft) long, 2.13 m (7 ft) wide, and 2.13 m (7 ft) high (wall height). The building was tested with interchangeable gable roofs with three different slopes (2:12; 5:12 and 7:12). The field tiles of these gable roofs were tested under three different tile profiles. namely: high (HP), medium (MP), and low profiles (LP) in accordance with Florida Building Code of Practice; but, only the MP profile is discussed in this paper. For the ridge part of the roof, two different types of tiles were considered, namely: rounded and three-sided. The results showed that the ridge tiles were exposed to high pressure coefficients as compared to the field tiles, including those located at the corners. Considerably higher pressure developed on the gable-end ridge tiles compared to those at the roof center. Positive mean underneath pressure on the field tiles develops on the windward side, thus increasing the net pressures on the windward surface of the roof. On the leeward side, however, reductions in net pressure to a non-significant level were observed due to the opposite direction of the internal and external pressures.

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.
