Tributary line load calculator

Tributary area (ft²)

Load intensity (psf)

Beam span (ft)

Total tributary load = 400 ft² × 80 psf = 32,000 lb

Service line load = 32,000 lb / 20 ft = 1600.0 plf

Factored line load (×1.6 live) = 2560.0 plf

Wind velocity pressure calculator

qz = 0.00256 · Kz · Kzt · Kd · Ke · V² (ASCE 7-22 Eq. 26.10-1, V in mph, qz in psf)

Basic wind speed V (mph)

Kz (velocity pressure exposure)

Kzt (topographic)

Kd (directionality)

Ke (ground elevation)

qz = 0.00256 × 0.85 × 1 × 0.85 × 1 × 115²

qz = 24.46 psf
