Structural Health Monitoring via Connectivity Constrained Reference Basis Model Updating

The paper presents a structural health monitoring method that is based on the model updating method connectivity constrained reference basis. The method combines two separate approaches, reference basis and parametric methods, and it is computationally efficient because it does not require calculation of sensitivity functions. The paper discusses why connectivity constrained reference basis is generally suitable for structural health monitoring and what are the modifications required in the new application. The derivation includes noise propagation analysis of the algorithm and its effect on the new structural health monitoring application.
