| 摘 要： | 采用节点柔度矩阵的方法，通过求逆和刚度平移矩阵最后形成曲杆单元刚度矩阵，采用卡氏第二定理求出单元荷载等效节点力，然后与节点荷载叠加，形成结构荷载．通过计算对比，精度大大提高．

| Abstract: | By computing the point flexible matrix of the curved beam element and inverting it, the curved beam element stiffness matrix can be derived by the stiffness translating matrix. The equivalent point force is worked out by the way of Castigliano＇s second theorem for the element load. All the loads are added to form the load vector of the structure. The computing accuracy is improved evidently. |
