| 中文摘要: |
| 基于非线性弹性理论，从单索的平衡出发，在索元的无应力长度已知情况下，提出了两跨连续索在中间节点滑移的初始平衡位置确定及均布荷载作用下的静力响应分析方法，建立了其非缄性计算的基本理论、公式和求解方法，并进行了实例计算。 |
| 英文摘要: |
| 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. |
