【 摘 要 】

Cryogenic liquefied-gas storage tanks are more and more widely used in engineering. As a typical pressure vessel with a complicated structure and working at a low temperature, it is critical to ensure the safety underall possible loadings. In this paper, a finite element model for a cryogenic liquefied-gas storage tank was established. Stress analysis and the strength as well as stability assessment under two load cases with different combination of loadings were performed. It is found that the cryogenic liquefied-gas tank subjected to the normal design pressure, wind and seismic loads is satisfied to strength requirement according to the JB4732-1995 Steel Pressure Vessels - Design by Analysis.
