| 摘 要： | 在理论和数值上分析了环向加筋圆筒储物仓的屈曲情况，获得了在侧压作用下的临界屈曲载荷．首先将环向筋条看作离散分布问题，用能量法进行较精确的理论分析；然后采用通用的有限元程序ANSYS模拟模型得到其数值解．结果表明，得到的数值解与解析解符合较好，有限元法是分析加筋圆筒储物仓屈曲问题的有效方法．

| Abstract: | The buckling of the ring-stiffened cylindric warehouse was analyzed theoretically and numerically and the critical buckling load under lateral pressure action achieved. The ring stripes taken as dispersible, the energy method was used to do more accurate theoretic analysis. To get numerical results, the general finite element program-ANSYS was employed to simulate model. The result indicated that the numerical solution was in good agreement with the analysis value, showing that finite element method was an effective way to analyze the buckling of ring-stiffened cylindric storehouse. |
