THE EXTRADOSED CABLE ANCHORAGE AND ULTIMATE BEHAVIOR FOR EXTRADOSED BRIDGE WITH CORRUGATED STEEL WEBS

Abstract

This paper reports experimentation which were conducted for the purpose of grasping the nonlinear behavior at the ultimate state and for the check of the safty of the proposed extradosed cable anchorage structure for extradosed bridge with corrugated steel web. From the experimental results, the safty of the proposed extradosed cable anchorage structure at the ultimate and design load was confirmed. It was also found that the nonlinear behavior of this extradosed bridge with corrugated steel web can be correctly predicted by nonlinear analysis by the fiber model in consideration of the rigidity of a corrugated steel web.
