空间过渡梁元的切线刚度矩阵

Tangential Stiffness Matrix of Transition Beam

详细推导了整体拉格朗日(Totallagrange)坐标系下空间过渡梁元的切线刚度矩阵和单元抗力计算式。计算表明,过渡梁元切线刚度矩阵的提出,使局部单层局部双层网壳的计算结果更趋近于实际。

In this paper,the tangential stiffness matrix and member resistant formula of transition beam are presented.Analysis shows that the tangential stiffness matrix of transitional beam can enhance the culculation precision of the partial single layer and partial double layer reticulated shells.
