Shear lag in a tension member connected through one leg of an angle causes the effective net area to be:
Choose the correct answer
Greater than the actual net area
Equal to actual net area always
Less than actual net area (reduction factor applied)
Zero
Correct Answer
C. Less than actual net area (reduction factor applied)
AI Detailed Explanation & IS Code Reference

Shear lag occurs when load is not uniformly distributed across the net section (e.g., single-leg connections). IS 800 applies an efficiency factor (0.6-0.8 depending on number of bolts) to reduce the net area, accounting for the non-uniform stress distribution.
