Multimodal distributions of some physics based model parameters are often
encountered in engineering due to different situations such as a change in some
environmental conditions, and the presence of some types of damage and
nonlinearity. In statistical model updating, for locally identifiable
parameters, it can be anticipated that multi-modal posterior distributions
would be found. The full characterization of these multi-modal distributions is
important as methodologies for structural condition monitoring in structures
are frequently based in the comparison of the damaged …
