Consider a doubly reinforced RCC beam with the option of using either Fe250 plain bars or Fe500 deformed bars in the compression zone. The modulus of elasticity of steel is 2x105 N/mm2. As per IS456:2000, in which type(s) of the bars, the stress in the compression steel ($f_{sc}$) can reach the design strength (0.87$f_{y}$) at the limit state of collapse?
(A) Fe250 plain bars only
(B) Fe500 deformed bars only
(C) Both Fe250 plain bars and Fe500 deformed bars
(D) Neither Fe250 plain bars nor Fe500 deformed bars
(A) Fe250 plain bars only
(B) Fe500 deformed bars only
(C) Both Fe250 plain bars and Fe500 deformed bars
(D) Neither Fe250 plain bars nor Fe500 deformed bars
Correct : a
