FBC 2023 · ASCE 7-22 · ADM 2020 — preliminary screening tool

⚠ Preliminary screening only. Order-of-magnitude check of an aluminum fence/railing under wind & guard loads. Not a sealed engineering document; not for permit or construction. No warranty or liability — verify all inputs and have a licensed engineer review. Need a sealed calc? →

Live Loads (FBC 1607.8) Apply guard live loads (200 lb & 50 plf)

Standard configuration for safety guards. For on-grade boundary fences, uncheck to apply pure wind pressure design cases.
Caveat: Fences mounted on retaining walls or decks with a drop-off > 30" legally become "Guards" and must resist 200 lb loads.

Section

Composite Snap Assembly Composite action — add HR-2 insert stiffness (Path A: ΣI)

Top rail = shell + HR-2 insert; post = shell + HR-2 insert. Enter the insert (HR-2) I & A from the EMS section data. ΣI feeds deflection AND stress (S=ΣI/c). Valid only if the snap legs develop the shear flow q=VQ/I — otherwise leave OFF (two separate tubes).
