What is Damage Mechanism in Post-Tensioned Bridges about?

The study investigates the damage mechanisms of post-tensioned concrete box bridges subjected to close-in deck explosions, using numerical simulations to analyze blast wave effects. It finds that while only a small percentage of the blast overpressure penetrates the deck, the confined conditions within the box amplify the blast waves significantly, leading to damage primarily in the anchorage zones of pre-stressing tendons. The results highlight the need for energy-absorbing systems to mitigate explosion im
