Gravity Load Takedown — Multi-Column

AS/NZS 1170.0 & 1170.1 · One floor schedule, multiple columns · Cumulative G & Q with live-load area reduction
Columns

One row = one floor, top → bottom. Each column has its own tributary area per floor (A columns). Units: m, m², kPa. Tick "Reduce Q" to apply the live-load area reduction (ψa = 0.3 + 3/√A) to that floor.
