| 摘 要： | 推导了变截面梁单元的扭转刚度矩阵和等效节点载荷公式。对于截面半径按线性变化的梁,运用该扭转刚度矩阵将得到精确解。对于变截面梁的扭转,若用等截面扭转刚度矩阵分段近似,需采用较多的单元数,才能使结果收敛于精确解。

| Abstract: | In the thesis the element torsion stiffness matrix and equivalent joint load are derived. The use of element stiffness matrix will produce exact solutions for members with linearly varying radius. As to the torsion of non - uniform beam, if using uniform the element stiffness matrix, one needs more elements in order to converge to the exact solution. |
