In case when plates are connected by zigzag or staggered riveting the net sectional area A net is given by
1
\(A_{n}=\left[b-n d_{n}+n^{\prime} \frac{P^{2}}{4 g}\right] t\)
2
\(A_{n}=\left[b+n d_{n}-n^{\prime} \frac{P^{2}}{4 g}\right] t\)
3
\(A_{n}=\left[b+n d_{n}+n^{\prime} \frac{P^{2}}{4 g}\right] t\)
4
\(A_{n}=\left[b-n d_{n}+n^{\prime} \frac{4 P^{2}}{g}\right] t\)
