EXAMPLE 8.5 A post-tensioned beam of rectangular cross-section, 200 mm wide and 400 mm deep, is 10 m long and carries an applied load of 8 kN/m, uniformly distributed on the beam. The effective prestressing force in the cable is 500 kN. The cable is parabolic with zero eccentricity at the supports and a maximum eccentricity of 140 mm at the centre of span.
