abstract = {One of the main structural components of cable-stayed bridges is the post-tensioned stay cables, which stretch diagonally from the pylons to support the horizontal deck. These essential members may be lost due to vehicular collision, excessive corrosion of connections, or wind dynamic forces. Design code provisions generally require that the bridge is designed considering the likely event of accidental loss of any one cable. However, the effect of this loss has not been studied in great detail. The present paper is part of a series of extensive parametric static and dynamic studies aimed at developing efficient design rules. In the paper, the response of a cable-stayed bridge to accidental breakage of any one stay cable is investigated. A comprehensive 3-D finite element model of the bridge is developed to provide realistic member internal actions. A 3-D cable element is utilized to represent the stay cables, and geometric nonlinearities are accounted for in the study. The static effect of loss of a stay cable on the structural behaviour of the deck is examined. The study builds on previously developed in-house optimisation method for evaluating the optimum post-tensioning cable forces.<br/> Copyright &copy; (2014) by the Society of Plastics Engineers.},
