| 摘 要： | 本文推导了断面可变形的多宝薄壁曲梁的单元刚度矩阵和荷载矩阵的公式。这些公式用两种方法推出,即为加权残量法和能量法。为了将有限单元法的计算结果对比于解析法和结构分析程序5(即SAP5),举了例题。

| Abstract: | In this paper the formulas for the stiffness matrix and load matrix of thinwalled elementary curved beams with deformable multicelled cross-sections are presented. These formulas are derived in two different ways, that is, they are derived bythe method of weighted residual values and by energy principles. In addition, forcomparinq the results of finite element method with those of the analyticalmethod and Structural Analysis Program 5, illustrative examples are presented. |
