| 摘 要： | 近年来,轻型钢结构门式刚架是钢结构建筑中应用相当广泛的一种结构形式。本应用基于有限元基本理论考虑剪切变形影响的平面梁元切线刚度矩阵,采用动坐标法编制了等截面门式刚架的几何非线性分析程序,应用该程序,讨论了屋面均布荷载作用下等截面门式刚架的整体稳定性能,并探讨了在不同设计荷载作用下,几何非线性对等截面门式刚架的工作性能的影响。

| Abstract: | In recent years, the lightweight steel portal-frame structure has been applied fair extensively in steel structures. Based on the theory of the finite element, this paper applies the tangent stiff matrix of plane beams considering shear deformation, makes the program of the structures geometrical nonlinear analysis used moving-coordinate method. Used this program, the overall stability of the portal frame with straight members loaded uniform on the roof is investigated;The effect of geometrical nonlinear on the structures under different design loads is studied. |
