Instead of evaluating ground motion at just two periods (0.2 seconds and 1.0 second), the new data maps evaluate ground motion across hundreds of periods. This provides a far more accurate representation of how a specific building will vibrate during an earthquake, especially on softer soils (Site Classes D and E). 4.

While the ASCE 7-22.pdf remains the legal and textual baseline, the physical wind, seismic, and snow maps have been largely superseded by the online ASCE 7 Hazard Tool . Instead of evaluating ground motion at just two periods (0

ASCE 7-22 establishes updated minimum design loads for structures, featuring significant revisions to environmental hazard assessments and the introduction of mandatory tornado-resistant design provisions. Key advancements include enhanced 500-year flood protections, refined seismic spectral maps, and updated wind velocity calculations.
