Abstract :
An adaptive method for the on-line identification of hysteretic structures under arbitrary dynamic environments is presented. In spite of the challenges encountered in the identification of the hereditary nature of the restoring force of hysteretic systems, it is shown that the proposed approach can yield reliable estimates of the hysteretic restoring force under a wide range of excitation levels and response ranges. The proposed method is verified through simulation studies and experimental tests conducted on a full-scale structural steel subassembly
