无论是底部剪力法还是振型分解法，地震工况下的最大应力点均位于支柱托板与壳体连结的位置，因此在球罐的抗震设计中需要引起足够的重视；设计者需要选择合适的托板结构以尽量降低a点的应力集中。

No matter the bottom shear method or the mode decomposition method, the maximum stress point under the seismic condition is located at the position where the strut supporting plate is connected with the shell, so enough attention should be paid to the seismic design of the spherical tank; the designer needs to select the appropriate supporting plate structure to minimize the stress concentration at point a.<br>
