【Abstract】 Recent progress of investigations on sensor deployment methods and their evaluation criteria in structural health monitoring are critically reviewed in the paper. Existing major sensor deployments are analyzed with emphasis laid on revealing their mathematical interrelationship and differences. In particular, the relationship between the Effective Independence method and the Modal Kinetic Energy method, the connections between the Effective Independence method and the QR decomposition method and MinMAC method, are discussed in details. Furthermore, a ladder structure is employed as a model to compare the discussed sensor deployment methods and traditional five evaluation criteria for sensor deployment methods. Finally, an evaluation criterion proposed by the author is discussed through its connection with two traditional evaluation criteria.更多还原
