| 摘 要： | 本文以3次B样条函数作为时域的试函数,用双配点法建立起一个分析结构动响应的单步计算格式.通过对算法精度和稳定性的详尽分析,找到了两个值得推荐的方案:条件稳定的四阶算法(C1)及无条件稳定的二阶算法(C2).这两个方案的算法特性与一些熟知算法作了比较. |

| Abstract: | In this article, a family of single step algorithms for strueture dynamic response analysis is constructed by means of two points collocation approach. The B spline of the third order is adopted as trial function in time domain. After a detailed observation of the accuracy and stability of these algorithms, two desirable schemes are recommended: a conditionally stable algorithm of the fourth order (C1) and an unconditionally stable algorithm of the second order (C2). Their computational behaviour is compared with some familiar algorithms. |
