Abstract

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.
