Influence of Cable Layout on The Seismic Response Of Cable-Stayed Bridges

During the last few decades, cable-stayed bridges have proven to be first-class structures providing vital transport links. For this reason more researches about these types of bridges are of vital importance since the concerned engineers and relevant academicians need to understand clearly the behavior of these bridges under seismic loading with different cable configurations. In this paper, a 269m span cable-stayed bridge has been studied; the fan and radiating types of cable configuration have been considered as study parameters for the purpose of evaluating the effect of cable configuration in cable-stayed bridges under seismic loading. The earthquake force was considered to act in longitudinal direction and then in the transverse direction of the bridge, the analysis results like axial forces, shear forces, bending moments, torsion moments, deck and tower displacements have been presented and compared for both fan and radiating cable layouts.
