详细推导了 Ｔｏｔａｌ Ｌａｇｒａｎｇｉａｎ（Ｔ．Ｌ．）描述下空间过渡梁元的切线刚度矩阵。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。
The tangential stiffness matrix of the beam of transitional space under Total Lagrangian (T.L.) Is deduced in detail. The proposed tangent stiffness matrix of transition beam element makes the calculation result of local single-layer local double-layer reticulated shell closer to reality.
