Abstract

![CDATA[In design of cable-stayed bridges, sudden loss of cables are usually associated with material as well as geometrical nonlinearities which may trigger progressive collapse of the entire bridge. Accordingly, the possible reasons of loss of cable would be the blast loadings, which is one of the concerned situations after 911 terrorist attacks. In this paper, detailed 3D finite element models of a hypothetical cable-stayed bridge deck is developed and analysed with material and geometrical nonlinearities included. A parametric study is undertaken to investigate the effect of blast loadings with different material properties, section properties and different amount of explosive materials, to determine damaged area, number of loss of shell elements as well as cable elements due to explosion. With regard to the results of FE analysis, it is concluded that the maximum 3 cables would be lost by the large amount of TNT equivalent material due to damage of the anchorage zone.]]
