Short Span (lx) - meters

Long Span (ly) - meters

Check Slab Type

Press to detect slab action (ly/lx ≥ 2 → One-Way) and visualize the tributary areas.

Slab thickness (mm)

Concrete density (kN/m³)

Ceiling load (POP) (kN/m²)

Dead Load override (kN/m²) — optional

If left blank, DL = (thickness_m × density) + ceiling load (POP)

Live Load (LL) - kN/m²
