摘要
本文用力法导出了等截面圆弧杆件的转角位移方程，使某些带有圆弧杆件的复杂刚架适用位移法，从而使内力计算工作得到简化．
By mean of force method,the slope-displacement equation used for the circular curved bar of a constant cross section is derived in this paper. The equation enables the displacement method to be used for frames with circular curved bars and simplifies the computation of inner forces.
