Updating Models and Their Uncertainties. II: Model Identifiability
Publication: Journal of Engineering Mechanics
Volume 124, Issue 4
Abstract
The problem of model identifiability is addressed. The goal is to find all the structural models within a specified class that produce the same output at a set of observed degrees of freedom as a given model in the class when they are all subjected to the same input. A new algorithm is presented to solve this problem for a class of multi-degree-of-freedom linear structural models, and the approach is illustrated with examples.
