To begin with, a series of reliability analyses of all cases in
Sample C are performed to study the effect of the COV component
of the model uncertainty. Four scenarios of model uncertainty,
each with c1=1.0 and a different COV
0.0, 0.1, 0.2, or
0.3, are studied. For each scenario of model uncertainty, 3 values
are calculated for all 64 case histories. Similar to the scenario
of no model uncertainty, a Bayesian mapping function can be
obtained for each model uncertainty scenario. While not shown
herein, the results indicate that within the range of 0–0.3, the
COV component of the model uncertainty has little effect on the
calculated probability.
Another series of reliability analyses of all cases in Sample C
are performed with four scenarios of model uncertainty, each with
COV=0.1 and a different c1
1.0, 1.1, 1.2, or 1.3. A set of
Bayesian mapping functions are obtained and shown in Fig. 3.
For the scenario of c1=1.0, which represents the case with Eq.

1 as the CRR model, PL=0.23 at =0, indicating that the CRR
model as expressed in Eq.
1 is quite conservative. As c1 increases,
the mapping function is shifted from left to right, and the
probability corresponding to =0 increases. An interpolated c1
value of 1.24 yields PL=0.5 at =0, which is believed to be an
accurate estimate of model uncertainty.
