Abstract

Bridges is the lifeline and important structure for any nation. Cable-stayed bridges are one of the most popular long-span bridge type due to its structural efficiency and pleasing aesthetics. Stays of cable-stayed bridges are critical structural elements which are subjected to corrosion, abrasion, wind, vehicle impact and malicious actions and these extreme loading scenarios may lead to severe damage and loss of cable which demands the progressive collapse analysis. Progressive collapse is a continuous spread and enlargement of initial local failure of structures, which is characterized by a disproportion between the initial failure and its resulting widespread collapse. Several bridge accidents occurred in recent years have demonstrated that the consequences of progressive collapse may be unpredictable and serious. It has been found that the ability to resist the collapse is determined not only by structural load-bearing capacity, but also by other structural attributes. Although great efforts have been contributed to the progressive collapse of building structures, comparably small attention have been paid in the same problem about bridge structures. In this research Xing jia bridge is consider with different geometry fan type , harp type & semi harp type cable system . Analysis of cable stayed bridge is done using computer programme SAP. Results obtained in form of Time period, Displacement and axial force are compared for different cable patterns. The results of the comprehensive evaluation of the cable failure show that the tread of the progressive failure of the cable-stayed bridges decreases when the location of the failed cables is closer to the pylon.
