| 摘 要： | 建筑物中预应力混凝土曲梁的应用越来越广泛，由此对圆弧形曲杆进行单元分析。本文根据结构力学基本原理导得圆弧形曲杆的单元刚度矩阵，采用相类似的方法以最一般的线性非均布集中荷载为例推得弧形曲杆的节点荷载列阵。

| Abstract: | The curved beam is increasingly extensively applied in buildings,so a curved element has been analyzed.The element stiffness matrix of the space circular curved beam is derived according to the theory of mechanics,the nodal load matrix is also derived similarly to the example of one general load. |
