摘要：In the principles of equal cable stiffness and equal cable strength, two cablestayed suspension bridges using CFRP cables with a main span of 800 meters were established. Threedimensional nonlinear method was taken to analyse the static charasteristis of the bridges in the finished state. Compared with the bridge using steel cables with the same structural arrangement, some conclusions were drawn about the effect of different cable materials on the static charasteristics of large span cablestayed suspension bridges. Under the condition of same structural arrangement, cablestayed suspension bridges using different cables show a similar flexural status. In the principle of equal cable stiffness, the CFRP bridge show better performance in strength and stiffness. While in the principle of equal cable strength, CFRP bridge show worse performance.
