| 摘 要： | 首先提出一种析的求解大跨径悬索桥静风扭转发散问题的方法－－三角级数法，这种方法综合考虑了静风荷载和和升力矩共同作用的非线性影响，然后导了了所有计算公式，给出了流程图，该方法具有输入数据少，计算速度快，易于编程的特点，最后，以江阴长江大桥为例进行了数值计算比较。

| Abstract: | Firstly, a new method used to solve wind-induced lateral-torsional buckling problems for long-span suspension bridges is proposed. Nonlinear influences caused by lift and pitching moment are included in this method.Secondly,fomulae and flow chart are provided. Finally, numerical results are presented to demonstrate the accuracy and effectiveness of this new method. |
