摘　　要：结构变形后以几何关系为基础，从轴向荷载对结构侧移刚度降低的角度出发，推导出有侧移刚架弹性屈曲的简化计算方法．该法计算简便、精度好，又有清晰的物理意义．Based on the geometrical relation that result from the deformation of structures, and the abatement of lateral stiffness in structures that result from the axial force, a simplified method for analysis the lateral elastic buckling in rigid frame is presented . Numerical examples are illustrated. The results obtained from the proposed method are quiet satisfactory as compared wity those by the precise method

关 键 词：弹性屈曲 侧移刚度 有侧移刚架 刚架
