摘要:	摘要： This study developed an integrated global-local approach for locating damage on building structures. A damage detection approach with a novel embedded frequency response function damage index (NEFDI) was proposed and embedded in the Imote2.NET-based wireless structural health monitoring (SHM) system to locate global damage. Local damage is then identified using an electromechanical impedance- (EMI-) based damage detection method. The electromechanical impedance was measured using a single-chip impedance measurement device which has the advantages of small size, low cost, and portability. The feasibility of the proposed damage detection scheme was studied with reference to a numerical example of a six-storey shear plane frame structure and a small-scale experimental steel frame. Numerical and experimental analysis using the integrated global-local SHM approach reveals that, after NEFDI indicates the approximate location of a damaged area, the EMI-based damage detection approach can then identify the detailed damage location in the structure of the building. 其他題名： ScientificWorldJournal 出版者： Cairo, Egypt: Hindawi Publishing Corporation 出版日期： 2014-01-01 出處： TheScientificWorld, 2014-01, Vol.2014 (2014), p.1-13 資源來源： DOAJ Directory of Open Access Journals [Accès libre] 版權： Copyright © 2014 Tzu-Hsuan Lin et al. 版權： COPYRIGHT 2014 John Wiley & Sons, Inc. 版權： COPYRIGHT 2014 Hindawi Limited 版權： Copyright © 2014 Tzu-Hsuan Lin et al.
