ABSTRACT
Stays of cable-stayed bridges are critical structural elements which are subjected to corrosion, abrasion, wind, vehicle impact and malicious actions and these extreme scenarios may lead to severe damage and loss of cable(s) (Walther 1999, Åkesson 2008). Such cable loss scenarios would lead to high impulsive dynamic loads in the structure that can potentially trigger a “zipper-type” progressive collapse of the entire bridge (Starossek 2011). Accordingly, cable-stayed bridges should be designed for potential cable loss scenarios as recommended by the PTI guidelines (2007).
