HYSD bars in either direction in RCC slabs should not be less than -------- of total cross-sectional area.
2) HYSD bars in either direction in RCC slabs should not be less than -------- of total cross-sectional area. ans-0.12 %. Concept According to IS 456:2000 , for reinforced concrete (RCC) slabs, the minimum percentage of reinforcement using HYSD (High Yield Strength Deformed) bars in either direction should not be less than 0.15% of the total cross-sectional area of the slab. This requirement ensures that the slab has sufficient reinforcement to carry the loads and control cracking, while also considering the use of high-strength steel like HYSD bars.
