Home » Concrete Structures » Concrete structures miscellaneous » Question

In the limit state design method of concrete structures, the recommended partial material safety factor (gm) for steel according to IS:456-2000 is

1. 1.5
2. 1.15
3. 1.00
4. 0.87

Correct Option: D

Design strength,

σ_d =	σ_k
	γ_m

σ_k = characteristics strength
γ_m for steel = 1.15
γ_m for concrete = 1.5
