Consider the given dimensions (Width × Depth × Unsupported Height) of RCC columns and identify the slender columns according to IS 456:2000 (where a column is classified as slender if its effective slenderness ratio with respect to any axis is 12 or more; assume effective length equals unsupported length for simplicity): Column 1: 450 mm × 450 mm × 3800 mm Column 2: 150 mm × 300 mm × 3650 mm Column 3: 200 mm × 450 mm × 3650 mm Column 4: 150 mm × 300 mm × 2500 mm Column 5: 300 mm × 300 mm × 3200 mm
