<正>Ever since the September 11~(th) event,researchers have paid great attentions to study the failure mechanism of building structures for protection of government buildings, embassies and military structures.However relatively less attention has been put towards bridge structures which play a crucial role in transportation network.In this paper,a detailed modelling of a cable-stayed bridge subjected to blast loads will be presented.Blast load considered is generated from a 1000 kg TNT equivalent explosive detonated at various locations in a close proximity of the bridge piers, tower and on bridge deck.LS-DYNA is used to model the bridge response and damage.From the results it is found that the 1000 kg TNT equivalent explosive causes more severe damage on pier and bridge deck as compared against tower for this particular bridge design.Therefore application of protective measures on pier and concrete deck is more critical for protection of this bridge against blast loading.
