Formulas: Combined Tension and Shear in Slip-Critical Connections

Equation J3-5a

When a slip-critical connection is subjected to an applied tension that reduces the net clamping force, the available slip resistance per bolt from Section J3.9 shall be multiplied by the factor, $k_{s c}$ , determined as follows:

k_{s c}=1-\frac{T_{u}}{D_{u} T_{b} n_{b}} \geq 0 \text { (LRFD) }

Formula 2

k_{s c}=1-\frac{1.5 T_{a}}{D_{u} T_{b} n_{b}} \geq 0 \text { (ASD) }

where

$T_{a}=$ required tension force using ASD load combinations, kips (kN)

$T_{u}=$ required tension force using LRFD load combinations, kips (kN)

$n_{b}=$ number of bolts carrying the applied tension
