摘要：Comparing probability density functions of ultimate
bending capacity of a “hybrid composite girder” with those of
“composite girder”, it can be found that the hybrid composite girder
shows higher reliability. In this paper, the numerical experiments
based on Monte Calro simulation is carried out and the effect of the
prior information is examined. The prior information easily given
from testing is the average and variance of the strength, elasticity
and other parameters of materials and of the dimensions of members.
The result says that these information gives same capacity even
under different assumptions for the probability density functions,
while the reliability considerably changes. However, it is also found
that the reliability of the hybrid composite girder is always much
higher than the normal composite girder.
