If you are designing from an older version, you are likely non-compliant. Below are the headline updates inside the .
The ASCE 7-22 document is intended for use by:
Because the hazard maps now reflect ultimate design snow loads, the snow load factor in LRFD load combinations drops from 1.6 to 1.0. Enhanced Rain-on-Snow Provisions
To ensure compliance with ASCE 7-22, designers and engineers should:
The seismic design provisions have seen a fundamental overhaul. The most impactful change is the shift toward data, which captures ground motion characteristics across 22 spectral periods. This provides a more realistic and detailed picture of how earthquakes of varying frequencies will impact a building. This new data also eliminates the need for the Fa and Fv coefficients used in previous editions, simplifying the process of calculating site-specific ground motions.
Flood load provisions now align closely with the latest FEMA guidelines and coastal high-hazard zone delineations, increasing required freeboard elevations in high-risk zones.
