摘要：

In this paper, our objective is to propose a state estimation-based damage detection method to enhance monitoring of structural health systems. The proposed method, which is called particle filter (PF)-based Shewhart chart, combines the benefits of the state estimation technique with the Shewhart control chart. The main advantages of PF-based Shewhart are twofold: (i) The PF is proposed to estimate the nonlinear states of a structural health monitoring (SHM) systems; (ii) The Shewhart chart is proposed to detect damages in the mean in the SHM systems. The performance of the proposed method is proved through the three degree of freedom spring-mass-dashpot system and the the effectiveness of the proposed method in damage detection is showed based on the presented results.
