| 摘 要： | 将割线刚度引入弧长法进行计算，以求解非线性有限元问题，这个方法的优点是可以不必计算各增量步引起的初始内抗力项，与原弧长法相比较计算量较小，程序也易于编制，可广泛用于求解非线性问题。

| Abstract: | The secant rigidity is used for the are-length method to solve the nonlinear finite elements problems. The advantage of this method is unnecessary of calculating the initial resistance term caused by the incremental step. The computational work is less and the programing is easier as compared with initial are-length method. This method can be widely used to solve nonlinear problems. |
