Linear/Nonlinear Dynamic Analysis and Prediction of Failure Mechanism of Irgandi Bridge

The goal of this study is to investigate the behavior and failure mechanism historical Irgandi Bridge located in Bursa City under earthquake loads by using linear nonlinear dynamic analysis. Dynamic characteristics bridge investigated in-situ Operational Modal Analysis (OMA) tests. finite element model updated according OMA Three different artificial records from weak very strong are applied for understanding damage zones bridge. results show that does not reach earthquakes However, even if occurred stiffness decreased, there no observed analyses. Under reaches As level increases, difference between analysis increases due structural damages. In addition, considering soil-structure interactions, it concluded could be reflected more accurately.
