Abstract

Cable pylons are important components of extradosed bridges. However, cable pylons pose difficulties in design and analysis because of their complicated loading conditions in the anchorage zone. In the present paper, taking the super-large Ningjiang Songhua River Bridge as the reference, a theoretical study of the crack resistance of concrete pylons in serviceability stage, and a numerical simulation analysis of the crack condition and stress distribution below the cable saddle constructed of parallel steel pipe are conducted using extended finite element method (XFEM) and the material nonlinear finite element method. The results obtained could provide a reference for the design and reinforcement of the pylon of similar bridges
