To determine how many Y12 bars can replace a Y16 bar in a column, you need to consider the area of steel provided by each bar. The area of a Y16 bar is approximately 201 mm², while a Y12 bar has an area of about 113 mm². Therefore, to replace one Y16 bar, you would need about 201/113 ≈ 1.78, meaning you would need at least 2 Y12 bars to provide a similar cross-sectional area of steel.
