Abstract
This study analyzes the potential economic impacts from implementation of the new tornado load requirements in the ASCE 7-22 Standard: Minimum Design Loads and Associated Criteria for Buildings and Other Structures, by incorporation into the International Building Code (Proposal S63-22 in Ref. [3]) and/or direct adoption by Federal, state, and local governments. The Standard requires that Risk Category III and IV buildings located in the tornado-prone region (approximately equal to the area of the conterminous U.S. east of the Continental Divide) be designed to resist tornado loads in addition to wind loads from other types of storms. Risk Category III includes buildings that represent a substantial hazard to human life in the event of failure (e.g., theaters and other assembly occupancies, schools, nursing homes), while Risk Category IV is for essential facilities (e.g., hospitals, fire and police stations, emergency operations centers).
