method of successive approximation

Application of successive approximation in analyzing non-linear earthquake response;

非线性地震反应时程分析中逐步渐近法的应用

The step by step approximation method can be used to the new phase segment,however,the mixed phase segment can only be solved by .

纯新相段可用逐步近似法,混合相段则必须用数值方法求解。
