摘　　要：本文只研究在刚架平面内发生弯曲屈曲的稳定问题。在刚架平面内，刚架的失稳形式必须针对刚架的组成和荷载作用的条件进行分析。位移法求解刚架屈曲荷载时，对于有轴心压力的构件，其转角位移方程需考虑轴心压力对构件抗弯刚度的影响，建立了平衡方程以后得到的是求解屈曲荷载的屈曲方程。This study had happened in the in-plane bending the stability problem buckling. In the frame, the frame of in-plane instability forms must be in frame composition and load conditions were analyzed. Displacement method to solve the frame buckling load, for the component and its axis pressure Angle displacement equation of component axis pressure should be taken into consideration, the influence of bending stiffness is established after the balance equation is solved the buckling equa- tion buckling load.
