Which risk increases when the rebar cage of a reinforced concrete column is misaligned before pouring?

A)Reduced buckling resistance of the column✓

B)Increased compressive strength of the concrete

C)Improved ductility of the steel reinforcement

D)Enhanced fire resistance of composite structure

💡 Explanation

When steel reinforcing cage is misaligned during pouring, the moment of inertia changes, causing decreased resistance to bending; the column can buckle more easily because critical load decreases. Therefore, reduced buckling resistance results, rather than strength gain, improved ductility, or fire resistance, which would require additives.
