| 摘 要： | 导出了有限条法分析环加肋圆柱壳在静水压力作用下总体屈曲的计算格式，将环加肋圆柱壳作为一个构造上的正交各向异性壳处理，推导了考虑环向加肋影响后有限条元的正交各向异性弹性矩阵。对两端简支环加助圆柱壳总体屈曲临界载荷的计算表明，本文方法计算结果与解析解符合良好。有限条法是分析密加肋圆柱壳屈曲问题的有效数值方法。

| Abstract: | The procedtires for the general buckling analysis 0f ring-stiffened cylindrical shells under hydrostatic presstlre by finite strip method are formulated. The stiffened shell is treated as a bare shell with orthotropic properties. The elasticity matrix of the strip is worked out. The buckling load of a simply supported ring-stiffened cylindrical shell by FSM compares favorably with the analytical solntion. It is shown that the finite strip method is an effective method for the buckling analysis of ringstiffened cylindrical shells with closely spaced stiffeners. |
