What changed in 7‑22? (short context)
- Wind provisions updated (basic wind speed maps, WBDR/Exposure clarifications). Verify W from your wind calc when switching 7‑16 ↔ 7‑22.
- Component & cladding guidance streamlined; roof zoning simplified in places.
- Tornado maps introduced for select regions (not included here; treat separately when applicable).
Methodology & Scope
This calculator assembles common ASCE 7‑16/7‑22 combination forms for LRFD (§2.3), ASD (§2.4), and service-level checks (Appendix C style). Wind & seismic inputs are effects obtained from your dedicated ASCE 7 wind/seismic calculations. Jurisdictional requirements govern.
