Plotting the cable zone
not rise above the top of the central kern if the stress on the bottom fi bre is not to
fall below zero. The top of the cable zone can thus be found by plotting a point
that is 16.51 / 9.38 = 1.76 m down from the top of the kern. As
a
t
= 0.488, the top
of the cable zone is at an eccentricity of 1.76 - 0.488 = 1.272 m. This is shown in
Figure 5.7 (a).
