Formula 1

(a) When Dt≤0.11EFy\frac{D}{t} \leq 0.11 \frac{E}{F_{y}}

Dt≤0.11EFy\frac{D}{t} \leq 0.11 \frac{E}{F_{y}}

Equation E7-6

Ae=AgA_{e}=A_{g}

Formula 3

(b) When 0.11EFy<Dt<0.45EFy0.11 \frac{E}{F_{y}}<\frac{D}{t}<0.45 \frac{E}{F_{y}}

0.11EFy<Dt<0.45EFy0.11 \frac{E}{F_{y}}<\frac{D}{t}<0.45 \frac{E}{F_{y}}

Formula 4

Ae=[0.038EFy(D/t)+23]AgA_{e}=\left[\frac{0.038 E}{F_{y}(D / t)}+\frac{2}{3}\right] A_{g}

where

D=D= outside diameter of round HSS, in. (mm)

t=t \quad= thickness of wall, in. (mm)
