, the column strip takes a larger proportion of the moment. For such cases, about
60-70% of
M
o
will be resisted by the column strip.
If you sketch in the approximate deflected shape of a panel, you will see that a larger
portion of the positive moment is carried by the middle strip than by the column strip, and
vice versa for the negative moments. As a result, about 60% of the positive
M
o
and about
70% of the negative
M
o
are expected to be resisted by the column strip.
