The information reflects the ASCE maps electronically to speed up critical design project information and displays easily for your convenience. Find out why. It provides the wind load calculations on uplift, leeward, windward and roof forces of a building. Standards are provided for minimum design loads (live, dead, snow, wind, rain, flood, ice, and earthquake as well as the required load combinations). The user can look up wind loads by inputting the address, latitude/longitude, or pin the location on the site map. Calculations courtesy ofAlex Tomanovich, PE. This is required in a lot of design or building codes and can often be the governing load case in areas with high winds. Use the Ground Snow Load for New Hampshire developed by the Corps Snow loads and wind speed load requirements are determined by your ZIP code and also built into the pricing and design software utilized by your metal building broker.
