Following recommendations from the National Institute of Standards and Technology’s investigation into the impacts of the deadly tornado that struck Joplin, Mo., in 2011, the International Code Council (ICC) approved building code changes for tornado-prone regions requiring enhanced protection for new school buildings and additions on existing school campuses, as well as facilities where people regularly assemble, such as gymnasiums, theaters and community centers. Additionally, storm shelters must be provided to protect occupants from storms with wind speeds of 250 mph. The storm shelter requirements will be published in the ICC’s 2018 International Building Code and 2018 International Existing Building Code.
