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 2 × 10 5 N/mm 2 . 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?

Correct Answer is : Fe250 plain bars only

Both Fe250 plain bars and Fe500 deformed bars

Neither Fe250 plain bars nor Fe500 deformed bars
