Asce 7-22.pdf [patched] Review

ASCE 7-22 establishes updated consensus-based standards for structural design loads, incorporating significant changes such as explicit tornado requirements, enhanced flood loads, and revised seismic, wind, and snow criteria. Key resources and summaries for navigating these updates include the FEMA Building Designer's Guide to Calculating Flood Loads and technical summaries from organizations like the Structural Engineers Association of Utah. Updated ASCE 7-22 standard now available

Introduction

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.
