(i) Characteristics strength of concrete, fck=20N/mm2
(ii) Characteristics strength of reinforcing steel, fy=415N/mm2
(iii) Width, b=250mm
(iv) Effective depth, d=317mm
(v) Neutral axis factor, xub/d
ccs
=0.0035/0.0035+0.0038
=0.48
(vi) Coefficient, Qub
=k1(xub/d)(1−k2(xub/d))
=0.36×0.48×(1−0.42×0.48)
=0.138
(vii) Moment of resistance due to concrete,
Muab =Qubfckbd2
=0.138×20×250×3172
=69.395kNm
Hence, the correct option is (c).
