摘要
考虑弯扭耦合，按结构力学方法推导出位移法中常用单跨超静定圆弧曲线梁的弯—扭转角位移方程，可直接用于矩阵位移法的单刚方程。通过算例验证了公式的正确性并说明了位移法分析平面曲梁杆系结构的计算步骤。
Based on the schemes of different support conditions of curved bridges, the rotation displacement and torsion equations are derived. Examples are gived for calculation procedure of curved continuous rigid frame and curved continuous girder.
