Question

Two bolted plates under tension with alternative arrangements of bolt holes are shown in Figures 1 and 2. The hole diameter, pitch, and gauge length are $d$, $p$, and $g$, respectively. Which one of the following conditions must be ensured to have higher net tensile capacity of configuration shown in Figure 2 than that shown in Figure 1?

Accepted Answer

p² > 4gd. For staggered bolt holes, the net width includes a correction term $\frac{p^2}{4g}$. Figure 2 has higher net tensile capacity than Figure 1 only when this gain outweighs the additional hole loss. That condition simplifies to $p^2>4gd$.
