Formulas: bearing strength

Equation J7-1

R_{n}=1.8 F_{y} A_{p b}

where

$\begin{aligned} A_{p b} & =\text { projected area in bearing, in. }^{2}\left(\mathrm{~mm}^{2}\right) \\ F_{y} & =\text { specified minimum yield stress, ksi (MPa) }\end{aligned}$

Formula 2

(1) When $d \leq 25$ in.

d \leq 25

Equation J7-2

R_{n}=\frac{1.2\left(F_{y}-13\right) l_{b} d}{20}

Formula 4

$R_{n}=\frac{1.2\left(F_{y}-90\right) l_{b} d}{20}$ (J7-2M)

R_{n}=\frac{1.2\left(F_{y}-90\right) l_{b} d}{20}

Equation J7-3

R_{n}=\frac{6.0(F_{y}-13)l_{b}\sqrt{d}}{20}

Equation J7-3M

R_{n}=\frac{30.2(F_{y}-90)l_{b}\sqrt{d}}{20}

where

$d =$ diameter, in. (mm)

$l_b =$ length of bearing, in. (mm)
