EXAMPLE 8.2 For the beam in Example 8.1, instead of axial prestresing, a curved cable having an eccentricity of 100 mm at the centre of span and reducing to zero at the supports is used, the effective force in the cable being 180 kN. Estimate the per- centage reduction in the principal tension in comparison with the case of axial prestressing
