| 摘要: |
| 本文用样条有限点法分析梁和基于Berger假设的板的几何非线性动力响应，推导了以样条结点参数表示的基本方程，用wilson-θ法求解动力增量方程，求得挠度响应曲线。本文的方法与有限元法比较，其计算时间省，程序简单，可在微机上计算。 |

| Abstract: |
| In this paper，the spline finite point method is presented for the geometrically nonlinear dynamic response of beams and plates based on Berger hypothesis. The essential equations in the sp1ine finite point method are deduced and the incremental equations are solved by means of wilson-θ method. The results show that the method in this paper can save computation time and make program simpler. As compared with the finit element method，It can be easily carried out on personal computers. |
