Structural response of cable-stayed bridge subjected to blast load

The recent increase number of terrorist attacks have accrued the vigilance from defense and securities organization of many countries. These entities collaborating with scientists allows providing a better insight into the structural performance of existing buildings subjected to pre-planned attacks. On the other hand, the explosive weapon is the most used methodology by the terrorists since they aimed to reach a consequent loss or damages. In this paper, the structural performance of a generic cable-stayed bridge under blast loading is assessed throughout an extensive numerical analysis. Firstly, a though non-linear analysis is performed to under the ultimate capacity of a generic cable-stayed bridge, then it was possible to simulate the damage induced by the dynamic effect of a high impact action and finally considering different magnitudes of impact load, the failure state of the bridge is highlighted.
