| 摘 要： | 考虑任意空间梁单元存在6个广义结点位移向量的一般情况。从虚功原理出发，严格地推导了空间梁单元刚度矩阵的表达式。所得到的结果与文献中其他方法导出的结果一致，补充了相关文献对空间梁单元刚度矩阵的论述。

| Abstract: | According to the principle of virtual work, the formulae of element stiffness matrix about space beam-element have strictly been deduced while considering that there are six generalized node displacements for arbitrary space beam.The deduced results are consistent with references, which show that all formulae in this paper are correct,and supplementary for references. They provide some basic theory for further engineering applications. |
