Abstract:In light of the shortcomings of current analysis methods, such as the parabola method, the segmental parabola method, and the segmental catenaries method, in calculating the main cable curve of a suspension bridge with inclined hangers between the main cable and the stiffening girder, the improved segmental catenaries method was put forward here. Nonlinear equations were deduced to express the main cable curve of a suspension bridge with inclined hangers. At the same time, a more efficient and simple nonlinear finite element calculation method was obtained through establishing the parameterized calculation model based on the APDL language in ANSYS software and by using the dynamic prediction method. The calculation results of Xinhai Bridge show that the proposed method here markedly enhances the calculating precision of the main cable curve and is feasible and effective in practical engineering. ? 2010 ASCE.
