For accurately obtaining the stress distributions of large oil storage tanks shell,an analytical method for solving the long-short cylindrical shells was proposed.

To reinforce the safety and reliability of large oil storage tanks, structural analysis under statically-strength and aseismatic research under dynamically-loading were done.

The steel plate for large oil storage tank has shorter development history,its microstructure and properties are demanded grindingly and affected by many factors,the compositions and production processes are controlled subtly,the difficulty of production technology is larger and the development and research in China are late.

New modeling method for finite element analysis of large oil storage tanks;
