按推导带刚臂平面梁单元的单元刚度矩阵的思路,推导出了带刚臂空间梁单元的单元刚度 矩阵。这种单元形式应用于大型复杂结构的空间分析中，既能显著减少单元结点数量，又能较好地模拟实际结构受力状态，能给计算带来很大方便.

The stiffness matrix of space beam element with stiffarm is reported in this paper,using the method similar to the plane beam element.Using this kind of element in the space analysis of large complicated structures can not only reduce the number of elements and joints remarkably,but also imitate the real structures quit...
