| Abstract: | By analyzing the stability of external pressure of the 10000 m^3 vacuum spherical tank without strengthening ribs and with different strengthening ribs, then comparing with the expense of the different constrnctions,reaching a conclusion that designing a 10000 m^3 vacuum spherical tank without stiffening ribs is a better plan than designing with ribs ; elaborating finite element analysis results of external pressure of this spherical tank. |
