Identification of Damage Induced by Earthquakes
Article
Full-text available
An approach for detection of earthquake-induced damage in buildings is presented. The method is based on contrasting the response measured at all available channels with that predicted by a partial observer model formulated using data from prior small events. It is shown that the approach can discriminate between structures that undergo significant...

Context 1
... basic damage identification scheme is restated next, namely, 1) Data from a non-damaging earthquake is used to compute Markov Parameters which are stored in [Y]; 2) The Markov parameters are used in subsequent earthquakes to obtain an estimate of what would have been the response if the system behaved the same as in the small non-damaging event and the discrepancies are used as a basic feature. As denoted in Fig.1, the estimate can be compared with the actual measured acceleration and a residual time sequence, defined as the algebraic difference between the predicted output and the measured output can be obtained. ...
Context 2
... ˆ Although the scheme in Fig.1 captures the idea being explored, the accuracy attainable in this basic implementation depends (among other things) on being able to characterize the input with sufficient accuracy. ...
