Structure design of spherical tank s tie Rods Cut from Steel Plates and Installed in the middle;

In these aiticle,these differents was pointed out,and by comparing these standards,some ideas for reference were put up,and some suggestions about using and administration of high strength low alloysteel spherical tanks electrodes were proposed.

The damage of spherical liquid-storage tank due to outburst and ruinous earthquake can result in serious deaths and economic loss.

Routine and analytical design methods for gas spherical gasholder are introduced, and their different features are discussed.
