For a bolted tension member, the net area at a bolt hole is computed by deducting:
Choose the correct answer
Gross area minus full bolt diameter x thickness
Gross area minus (bolt diameter + 2mm) x thickness
Gross area minus (bolt hole diameter) x thickness
Gross area minus bolt shank diameter x thickness
Correct Answer
C. Gross area minus (bolt hole diameter) x thickness

Net area = gross area - (hole diameter x thickness). Hole diameter = bolt diameter + clearance (usually 2 mm for standard clearance holes, so hole diameter = nominal bolt diameter + 2 mm). IS 800 uses actual hole diameter for deduction.
