| 摘 要： | 用传递矩阵方法求解了圆柱壳端部局部轴压下的强度与临界载荷以及快堆主钠池组合壳在钠池地震晃动压力下的强度与稳定性。给出了两种边界条件下的临界地震系数ｋ＝１２．１和ｋ＝５．０，远超过八级地震允许值。数值计算结果表明传递矩阵方法求解旋转壳是有效的、可靠的。

| Abstract: | This Numerical treatment of cylindrical shell under the four axial
concentrated forces at the one end was made by the improved transfer matrix method. Its
internal resultants and critical load were given. Another example is the analysis of stresses
and stability of cylinder hemi sphere combined shell of the main Nadium pool of FBR. The
values 12.1 and 5.0 were assigned to the critical seismic factor k under 2 different boundary
conditions. These values are greater than that of the earthquake of class 8. The results of the
calculation show that the main pool of FBR is enough safe. |
