This technique extends an earlier methodology for structures with a predominant fundamental mode, to multi-degree of freedom situations. The structural behavior is evaluated in the form of a performance curve of the predominant response, as a relationship between the equivalent force and equivalent displacement. This curve, scaled by its corresponding mass ratio may be directly compared to a seismic demand curve for the purpose of condition assessment. In this paper, the decomposition procedure of dynamic structural response using the wavelet transform method is presented. Validity of the procedure is illustrated based on an actual dynamic response data from the Vincent Thomas Bridge (VTB) during the 1987 Whittier earthquake, the 1994 Northridge earthquake, and two ambient vibration events in 2004 are studied. 000010596 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000010596 653__ $$aHealth monitoring, Quick Inspection, Aftershocks, Seismic performance 000010596 7112_ $$a14th World Conference on Earthquake Engineering$$cBejing (CN)$$d2008-10-12 / 2008-10-17$$gWCEE15 000010596 720__ $$aKusunoki, Koichi$$iElgamal, Ahmed$$iTeshigawara, Masaomi$$iConte, Joel P. 000010596 8560_ $$ffischerc@itam.cas.cz 000010596 8564_ $$s293579$$uhttps://invenio.itam.cas.cz/record/10596/files/11-0042.pdf$$yOriginal version of the author's contribution as presented on CD, Paper ID: 11-0042. 000010596 962__ $$r9324 000010596 980__ $$aPAPER
