The group is recognized for technical innovations in conceiving and developing probabilistic tornado hazard maps and tornado load methodology for the United States. These first-of-their-kind maps scientifically account for the increased risk of a tornado strike with increased facility size. The group also is recognized for efforts to incorporate these maps and load provisions in the American Society of Civil Engineers' 2022 national standard for Minimum Design Loads for Buildings and Other Structures, thus enabling tornado-resistant design of U.S. buildings for the first time.
