In case of staggered or zigzag riveting in the design of tension members of steel structures, the net cross-sectional area along the chains of rivets is:
1
increased by an amount equal to \(\rm \frac{s^2t}{8g}\)
2
increased by an amount equal to \(\rm \frac{s^2t}{4g}\)
3
decreased by an amount equal to \(\rm \frac{s^2t}{4g}\)
4
decreased by an amount equal to \(\rm \frac{s^2t}{8g}\)
