Warehouse portal frame — analysis engine

AS/NZS 1170 gravity / wind / snow / seismic → NZS 1170.0 combos → member forces + SLS deflection + NZS 3404 §6.3 member checks.

engine loaded — awaiting input

Loadings — tributary line load on each frame (pick a load case; pressure × the frame's own tributary → kN/m)

Run an analysis to populate the load diagram.

Frame response (N · V · M · deflected shape, drawn on the real frame)

Member & deflection checks (worst case · governing load case per member)

Deflections & drift (SESOC Tables 4.1/4.2 SLS limits · seismic ULS elastic drift 2.5% h)

Run an analysis to populate the deflection checks.

Bracing & wind columns (longitudinal members — along-ridge wind path)

Run an analysis to populate the longitudinal checks.
