  12)  Mild steel bars in either direction in RCC slabs should not be less than -------- of total cross-sectional area ans - 0.15 % Concept In RCC slabs, mild steel reinforcement in either direction should not be less than 0.15% of the total cross-sectional area.  Here's a more detailed explanation:  Minimum Reinforcement: As per IS 456:2000, the minimum reinforcement in either direction of a slab using mild steel should not be less than 0.15% of the total cross-sectional area. HYSD Bars: If high-strength deformed bars (HYSD) are used, the minimum reinforcement in either direction should not be less than 0.12% of the total cross-sectional area. IS 456:2000: These guidelines are based on the Indian Standard code IS 456:2000, which provides detailed recommendations for the design and detailing of reinforced concrete structures.

  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.
