Abstract:
For determining the cable shape of suspension bridge with spatial cables at dead load. A three dimensional analysis model is presented in this paper based on the existing two dimensional method. Directly from geometry and equilibrium equation of three dimensional cable a iterative method to compute cable shape has been deduced. In the method, the geometry of main cable is projected onto two planes to consider the geometry boundary conditions and force equilibrium respectively and the effect of inclined hanger is also considered. The gradient method is used to deduce the iterative equation of three dimensional main cables. A program CF3D to analyze the shape of three dimensional main cables at dead load is compiled using C++ language. Based on the presented method and program a suspension bridge’s main cable shape at dead load was computed by iterative method. The results show that the accuracy of this method can meet the requirements of engineering calculations completely; the iteratively calculated cable shape is smooth. The method is accurate and convenient and applicable to multi-span suspension bridge with spatial cables.
