In steel tension member design, net effective cross-sectional area for a plate with staggered rivet holes is increased compared to chain riveting because:
AGross area increases
BStaggered pitch distance adds positive terms (s^2 / (4g)) to net width
CRivet hole diameter is reduced
DStress concentration factor is zero
Explanation
For staggered hole patterns, net width net_b = b – n*d + Sum[s^2 / (4*g)]. The added term increases net effective area.
