THE INFLUENCE OF BROKEN CABLES ON THE STRUCTURAL BEHAVIOR OF LONG-SPAN CABLE-STAYED BRIDGES

The influence of broken cables on the structural behavior of long-span cable-stayed bridges is examined considering all the nonlinear characteristics of a long-span cable-stayed bridge. The results show the influences of the broken cable on the structural behavior, such as the internal force, displacement, and the ultimate load-bearing capacity, are clear when an outside cable breaks. The results of the present study should assist in deciding when to replace cables in long-span cablestayed bridges.
