| Résumé | The wind loading provisions in the National Building Code of Canada (NBCC) have not been updated for decades despite developments in wind tunnel methods since the original source data. This study aims to review the NBCC 2020 provisions compared to wind tunnel experiments, field measurements, and the ASCE 7-22 provisions for single and multi-span gable roof buildings. Field measurements and wind tunnel tests are used to collect data: both for isolated building the later for multi-span gable. The wind turbulence and surface pressure measurements from the field agrees well with that of the wind tunnel experiments. The results provided evidence that NBCC provisions for single-gabled roofs (with slope 7°<α≤27°) and multi-span gabled roofs (with slope 10°<α≤30°) are currently underestimated. New provisions are suggested for the three roof zones (Zones c, s, and r) of the single-span gabled roof and for Zone s’ of the multi-span. It is suggested to merge Zone s into Zone c to form a new Zone p for the single gabled roof and to merge Zone s’ into Zone c for the multi-span gabled roof. The proposed changes correct the current provision underestimation and add simplicity for easier construction. |
