The ASCE/SEI 7-22 standard, Minimum Design Loads and Associated Criteria for Buildings and Other Structures

• Clarifies terminology and establishes reference documents.
• Sets design performance objectives tied to load and resistance factors.

Some of the key features and benefits of ASCE 7-22 include: The ASCE/SEI 7-22 standard, Minimum Design Loads and

Design process implications (practical)

• Update wind and seismic design inputs: check maps, site class, exposure and importance factors per ASCE 7-22.
• Re-evaluate rooftop equipment anchors, cladding attachments, and solar array detailing per updated wind/ice/rain rules.
• Perform ponding and rain-on-snow checks for flat/low-slope roofs; consider drainage upgrades where required.
• For seismic regions, reassess Sds, Sd1 values, and consider updated R, Ω0 or other factors for structural system selection.
• Consider nonstructural component anchorage early—ASCE 7-22 increases expectations for restraint and drift compatibility.
• Use wind tunnel testing or analytic wind loads for unusual geometries; ASCE 7-22 expands when these are required/recommended.
• Where tsunami or updated flood hazards apply, incorporate evacuation, foundation, and flood-resistant design requirements.

• Updated wind speed maps (3-second gust, 3-second/50-year exposures) and directionality factors.
• Refined external/internal pressure coefficients for a wider range of building shapes.
• Procedures for wind tunnel or analytical methods for complex structures.
• Requirements for rooftop equipment and cladding, and checks for uplift, overturning, and stability.

The implementation of ASCE 7-22 will likely have a significant impact on the engineering and construction industries. Some of the potential implications include: Clarifies terminology and establishes reference documents
