Inland II Zone. In areas with heavy snowfall, the snow load on a structure can be quite significant and must be taken into account during the design process. SkyCiv offers a full design report to show the calculations of the wind and snow pressures, so you can see exactly how the software calculated the wind pressures for ASCE 7-10/ASCE 7-16, EN 1991-1-4, NBCC 2015, AS/NZS 1170.2, IS 875-3, NSCP 2015, CTE DB SE-AE, and CFE and the snow load for ASCE 7-10/ASCE 7-16, EN 1991-1-3 (select countries), NBCC 2015, and AS/NZS 1170.3. Broken windows, doors and garage doors can result in internal loads that amplify the forces and increase the risk of structural damage. And In addition to the snow load zone, this tool can determine a wind zone as well as an earthquake zone for any location. To assist in your wind loading analysis, use the following wind load calc to get the necessary wind load calculations. Wind loads for torsional cases are 25% of respective transverse or longitudinal zone load values. The first step of the software is to pull the wind speed or ground snow load out of the design code based on the user input location or zip code. Contact Local Building Officials for determining required Snow If wind loading analysis is not done correctly the resulting effects could include collapsed windows and doors, ripped off roofing, and more.
