Özet

The structural performances of long span cable-stayed bridges having different elements such as pylons, stayed cables and decks are very sensitive to earthquake ground motions due to their highly statically indeterminacy. Therefore, responses of pylon, cable and deck components of long span cable-stayed bridges should be continuously monitored to prevent structural damages. The present study aims to investigate the responses of pylons, stayed cables and deck components of Nissibi cable-stayed bridge during the main (M w = 5.5) and aftershocks (M w = 3.5-4.4) of Adıyaman-Samsat (Turkey) earthquake on March 2, 2017. Firstly, the properties of structural and fixed monitoring systems of Nissibi bridge are introduced, and active faults and earthquake zoning maps of Adıyaman, acceleration records and shake map of main and aftershocks of the earthquake are presented. Then, responses of the pylon, deck and cable elements during the main and aftershocks are obtained using the data taken from the fixed bridge monitoring system. The forces in cables and accelerations in the two pylons and deck are evaluated and compared with each other. © 2019, Springer Nature Switzerland AG.
