Damage Assessment of an RC Pier under Noncontact Blast Loading Based on PI Curves

Abstract: Since the 9.11 attacks in New York, terrorist attacks, military strikes, and accidental explosions have caused serious damage to various infrastructures around the world. Accidental traffic explosions in bridge engineering have occurred frequently due to the increasing firework truck on the bridge and heavy fuel oil ships under the bridge. Besides, intentional car bomb explosions in terrorist attacks and military assaults are significant threats to the bridge structure. Bridge pier is a particularly important … Show more

This model disregards the effects of the local modes of failure, which can lead to an inaccurate prediction of the post-loading structural condition, especially when the loading is impulsive (G. W.
