A simply supported beam has a clear span of 6.5 m and is subject
to an external uniform service dead load wD = 15
kN/m (including beam weight) and live load wL = 36
kN/m. Preliminary design requires a rectangular section of width b
= 275 mm and effective depth, d = 425 mm with f’ c = 28 MPa and fy
= 415 MPa. Design the required area of steel
reinforcement for tension and
compression with the following assumptions:
