ABSTRACT
Over the last few decades, there has been a significant increase in the health monitoring and safety management field of the complex structure. The primary goal of the structural health monitoring is to find changes of system parameters and to decide its soundness at earliest possible stage. There are two categories in structural health monitoring and damage assessment whether structural model, such as stiffness, damping and mass information exist or not. One is model based scheme and the other is non-model based scheme. In model based scheme, system parameters are estimated by inverse analysis based on the sensitivity method from a mathematical model. In non-model based scheme, structural soundness is evaluated by pattern recognition and statistical approach from only measured signals without a structural model.
