摘要

Most wind loadWind loads provisions in the National Building Code of Canada (NBCC) were developed in the 70s and 80s. Since then, the Canadian provisions have remained practically unchanged. The National Research Council of Canada (NRC) is conducting an extensive wind loadWind loads investigation to verify whether current NBCC provisions need to be updated. The investigation uses field measurementsField measurements obtained from “in-service” buildings complemented with wind tunnel experimentsWind tunnel experiment. This paper focuses only on the field component of the project. The paper provides details of the experimental methodology, including data gathering and data analysis for Code comparison. To ensure the reliability of wind data, a systematic scrutiny procedure is implemented to isolate portions of data (segments) that are closer to stable atmospheric conditions and satisfy stationarity.
