ultimate shear strain. For example, the maximum shear strain ratios (
R
γ
) are approximately
equal to 40, 27 and 16 for panels G-0-0.54, G-0-1.2, and G-0-2.7, respectively.
Figure 6.39 gives the values of shear energy dissipation factor

as a function of steel
percentages (
ρ
or
ρ
t
) for panels in the A0 and A45 series. Two trends are evident: (a) the
factor
µ
D
for panels in A0 series is about two orders of magnitude larger than that in A45
series; and (b) the factor
µ
D
decreases with an increase of steel percentage from 0.54 to 2.7%
for panels in both the A0 series and the A45
◦
series.
