| 摘 要： | 通过有限元方法对某工程实例中150m单筒式钢筋混凝土烟囱进行了内力、位移计算及非线性屈曲分析。同时，介绍了钢筋混凝土烟囱的屈曲形式及计算烟囱整体稳定下的临界荷载，得出了单筒式钢筋混凝土烟囱无需计算整体稳定的结论，加强了对烟囱设计规范的理解，为单筒式钢筋混凝土烟囱的设计提供参考。

| Abstract: | Structure internal force,displacements, nonlinear buckling analysis of a 150 meters high single tube reinforced concrete chimney structure of one practical project is studied by FEM. Meanwhile, buckling form and critical force of reinforced concrete chimney is introduced to prove that overall stability of single tube reinforced concrete chimney is satisfied, so that it could not be calculated in design. This conclusion can be referenced to the design of single tube reinforced concrete chimney. |
