    Jabacus - Wind Load Calculator

    Uploaded by

    harishram123456
    The document is a wind load calculator that provides wind load calculations for a building project in Labrador City, Newfoundland, Canada based on the National Building Code of Canada 2010. It calculates external wind pressure and internal wind pressure for different roof slopes and sides of the building based on specified wind speed, terrain exposure, height, and other factors. The results show wind pressures ranging from -2.0 kPa to 1.15 kPa for ultimate and serviceability limit states depending on the building orientation and side.
