= 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: Initial partial tensile area with steel ratio corresponding to a tensile strain of 0.005 Reduction factor of 0.9 Effective depth of compression bars, d' = 65 = mm Box all final answers.
