Abstract

 This paper presents the study of cables rupture effect on cable-stayed bridges. The static and dynamic analysis for cable stayed bridge having five spans considering single plane of cables in harp shape is carried out. This study is concerned about bridges having five spans with 140 ms for exterior spans and 280 ms for the three interior spans. The total length of the bridge is 1120 ms. it's carried out for harp bridges. The own weight of all structural elements, and traffic load including impact are taken into account. In the both static and dynamic analysis, the energy method, based on the minimization of the total potential energy (TPE) of structural elements, via conjugate gradient technique is used. The procedure is carried out using the iterative steps to acquire the final configurations. Then, Dynamic Analysis is carried out for the most critical case to confirm the obtained results from static analysis. All prepared computer programs in FORTRAN language for this work and their verifications is written by [1]. All results showed that, the most critical case is the rupture of the outer cable (longest one). The conclusions, which have been drawn from the present work, are outlined.
