Calculate the required area of flexure steel bars for a balanced rectangular section of a simply supported beam 3.5 m long, sustaining a total uniform service load of 15 kN/m and a concentrated service load of 50 kN at midspan. Use Working Stress Design Method with b = 0.5d, f'c = 21 MPa, fs = 170 MPa, concrete cover of 40 mm, stirrup diameter of 10 mm and rebar diameter of 16 mm. Philippines
