Historically, US building codes did not mandate explicit tornado design for standard buildings. ASCE 7-22 changes this by introducing a dedicated chapter for tornado loads. This applies primarily to Risk Category III and IV structures located in tornado-prone regions of the Central and Eastern United States. Digital Wind and Snow Speed Data
ASCE’s newer interactive digital platform, AMPLIFY, provides access to ASCE 7-22, 7-16, 7-10, and ASCE 41-23, plus Tier 1 Checklists. This platform replaces the previous ASCE 7 Online interface and offers enhanced features for accessing standards digitally. For subscription inquiries, contact amplifytools@asce.org.
ASCE/SEI 7-22—titled Minimum Design Loads and Associated Criteria for Buildings and Other Structures —is the nationally adopted loading standard for general structural design in the United States. Developed by the American Society of Civil Engineers (ASCE) through the Structural Engineering Institute (SEI), this standard prescribes design loads for all major hazards, including:
Uses hundreds of periods to plot a more accurate seismic curve. asce 722pdf link
While the full standard is not free, ASCE provides several official resources at no cost that are essential for working with the standard:
For professionals, obtaining the official from the ASCE store is the first step. From there, leveraging the ASCE 7 Hazard Tool , studying the key changes from ASCE 7-16 to ASCE 7-22 , and understanding the addition of tornado loads and the major revisions to flood , snow , and tsunami provisions will equip you to meet the challenges of modern structural design. By embracing these updated requirements, engineers are not just complying with a code—they are actively building a safer and more resilient future.
