| Abstract: |
| According to the nonlinear theory elastically, and in terms of the equilibrium of single cable, a nonlinear analytical method of initial equilibrium and static response for the two\|span continuous cables sliding on the middle supporting was presented in this paper. The nonlinear computation formula and the calculation method and steps were established. The method can be used to compute the initial prestressed configuration of the above cable structures if the unstressed length of cables is given and to analyze the nonlinear static response under the uniformly loading along the cable's length. The results of two examples show that the method presented in the paper led to good precision in comparison with the numerical method. |
