摘　　要：用转角位移法对柱脚固接的刚架进行了弹性稳定分析 ,给出了刚架发生无侧移对称屈曲和有侧移反对称屈曲时的屈曲方程 。The elastic stability of rigid frame with fixed-base is studied in this paper.By use of te slope-deflection method,the buckling equations and the effective length factor of rigid frame in sway and no-sway buckling modes are obtained.

关 键 词：屈曲 转角位移法 单层单跨刚架 弹性稳定分析 计算长度系数 柱脚刚接
