In IS 800, the 'net effective area' for a tension member with staggered bolt holes is calculated using:
Choose the correct answer
Only the direct path perpendicular to load
All potential failure paths: direct + staggered (adding s²/4g for each diagonal step) — critical minimum net area governs
Gross area minus only one hole diameter
Reduced by 50% automatically
Correct Answer
B. All potential failure paths: direct + staggered (adding s²/4g for each diagonal step) — critical minimum net area governs

IS 800 Cl. 6.3 (staggered holes): Tdb using net area considering all possible failure paths. For staggered holes: effective net width = gross width − sum(hole widths along path) + Σ(s²/4g) for each stagger (s = stagger pitch, g = gauge). Check multiple potential failure paths and use the critical (minimum area) one. Ensures correct section is checked for net tension.
