The dimensions of a rectangular beam are limited to b = 300 mm and effective depth, d = 700 mm. Using f’c = 28 MPa, long bar fy = 415 MPa, calculate the required amount of tensile reinforcement so that a tensile strain of 0.005 is attained under a sustained ultimate bending moment of 1,200 kN.m. Compression bars centroid is 70 mm from beam edge.
