| 摘 要： | 本文介绍了多分辨率分析的基本概念，用分段三次Ｂ样条函数作为尺度函数建立了一种多分辨率梁单元。这种新单元除了能象一般梁单元使用之外，还可用于自适应分析法去求解梁的局部动力特征。它列式简单，在用直接法求解的系统中长法效率较高。

| Abstract: | In this paper, the conepts about the multiresolution analysis are intreduced. By taking the piecewise cubic B-spline as the scale function, a multiresolution bearn element is developed. Besides, being used as the usual beam elemnt, this new elernent can also be used in adaptive anaysis to find the local dynamic features of the structure. The formulation is simple and the algorithm is with high efficiency when used in direct solution System. |
