Ground snow PSF (pounds per square foot) and wind velocity & exposure level (MPH @ B or C exposure) help determine the appropriate size and configuration of a VersaTube building package. These loads can be either static, meaning that they are constant over time, or dynamic, meaning that they change over time. How can I switch to full-screen mode on the Geo-Zone Tool website "Snow Load, Wind Speed, and Seismic Load Maps"? From our perspective, the method in Para 1609.6 appears to be a simplified method that is intended to be used by a Designer looking up values in Table 1609.6.2. There are some other special considerations when following FBC 17. Understanding and properly accounting for wind loads is essential for ensuring the structural integrity of a building or other structure. There will be a highlighted note if your location is in a "wind-borne debris region" that requires impact protections for windows and doors. The zip code wind speed will then show the town or city (in this example Champaign, IL) as well as confirm the zip code entered (61820).
