摘要
利用力法推导出直角坐标下空间圆弧形曲梁的单元刚度矩阵,编制了含此类单元的空间刚架内力计算程序,并计算了工程实例.
The element stiffness matrix of the space circular curved beam for right-angled coordinate with the flexibility method are derived, a computer program including this kind of element for analysing the internal force of space frame is worked out and two engineering examples are calculated.
