摘　　要：随着大型储液罐在石化工业的广泛应用,其震害分析变得极为重要。利用ANSYS软件在空锚固式储液模态分析的基础上,输入模拟的地震加速度反应谱,得出了横向地震力作用下的较为精确详尽的储罐响应结果,直观的再现了空储液罐在地震力作用下的受力情况和薄弱环节,从而为储液罐的设计提供了可靠的依据,为进一步分析大型储液罐充液状态时的地震反应起到抛砖引玉的作用。Now earthquake can not be detected accuratly in advance, so it is important to analyse carefully dynamic response of structure under earthquake force and design reasonally to liquid storage tank as one of chemical equipment which suffer the most when earthquake happens . In this paper, spectrum analysis of an empty anchored liquid storage tank has been carried out after its model analysis . Then accurate conclusion of liquid storage tank response under X - direction earthquake force has been abtained. From the conclusion,we can get a reliable result that can directly adopted for design and use of liquid storage tank safely.
