摘要： 以欧美标准中的单包容与全包容低温储罐中的钢制储罐抗震设计方法为分析对象，从抗震设防水准与目标、抗震设计反应谱以及抗震设计准则如地震作用调整系数、阻尼比、载荷组合、抗震许用应力、抗倾覆与滑移、晃动波高等方面进行分析对比，为欧美低温储罐抗震设计方法的工程应用提供参考。为实现抗震设防目标以及与该国(区域)建筑抗震以及荷载标准体系协调，欧美低温储罐抗震各设计准则均存在一定的差异，工程设计时应合理应用以避免安全隐患。

Abstract:

Taking the seismic design methods of steel storage tanks in single containment and full containment low-temperature storage tanks in European and American standards as the analysis object, the seismic design response spectrum and seismic design criteria such as seismic action adjustment coefficient, damping ratio, load combination, seismic allowable stress, anti-overturning and anti-sliding, sloshing wave height and so on are analyzed and compared, so as to provide reference for the engineering application of seismic design methods of low-temperature storage tanks in Europe and America. In order to achieve the goal of seismic fortification and coordinate with the national(regional) building seismic and load standard system, there are certain differences in the seismic design criteria of low-temperature storage tanks in Europe and America. It should be reasonably applied in engineering design to avoid potential safety hazards.

Key words: low temperature storage tank, response spectrum, seismic design, seismic load
