Real-time hysteresis identification in structures based on restoring force reconstruction and Kalman filter

摘要

A real-time hysteresis identification method hasbeen established based on restoring force reconstructionand the Kalman filter. In proceeding so, a newhysteretic loop identification framework is proposedwhere rather than identifying the parameters of prescribedhysteretic models, the restoring forces are reconstructed.The Kalman filter is adopted for restoringforce reconstruction and it is shown that the additionalaugmentation of the restoring forces as statevariables acts as the role of Tikhonov regularization.
