Dynamic Response of Concrete Arch Bridge under Blast Loading
In order to reduce loss of terrorist attacks or accidental explosion accidents to traffic facilities of the state and society, antiknock safety of long-span bridge needs to be further studied. A deck arch bridge calculation model of fluid-structure interaction was established, and explicit dynamic analysis was presented to study the dynamic response of long-span arch bridge under blast loading, and the explosion effect to the overall structure of the bridge was analysed. The results show that the area around explosion center, has local large deformation and heavy damage degree, while a little far region has low deformation and damage degree; When explosives is located on the deck, the damage of blast-impact load on the main arch ring can be neglected, which is advantageous to the late bridge repair work. The results of this article can be provided as important theoretical reference to antiknock and explosion-proof of bridges in the future work.
