The National Institute of Standards and Technology started working toward its goal of a wind-load standard for tornado-resistant design after a tornado devastated Joplin, Mo., on May 22, 2011. A decade later, on Dec. 1, NIST reached its goal when the American Society of Civil Engineers Structural Engineering Institute published the 2022 edition of its bible on design loads. ASCE/SEI 7-22 contains, for the first time ever, a chapter on tornado resistance.
