Advanced BEEM Technique for Damage Inspection and Health Monitoring of Structures

In this paper we present a new version of Boundary Effect Evaluation Method (BEEM) BEEM with capabilities dramatically enhanced by our newly developed time-frequency signal processing techniques and nonlinear system identification methods, including an advanced time-frequency analysis technique based on Hilbert-Huang transform and a newly derived conjugate-pair decomposition method for online frequency tracking and health monitoring of structures. Numerical and experimental results obtained from several structures will be used to demonstrate this new version of BEEM.
