| 摘 要： | 采用ANSYS有限元软件，分别在锚固和非锚固情况下对某2万m3储液罐进行了隔震前后的地震响应分析，并考查了隔震装置的隔震基频和阻尼比的变化对储液罐隔震的影响。以动力响应中的最大应力值来评价隔震装置的隔震效果，以此分别确定了储液罐在锚固和非锚固状况下隔震装置的最佳隔震基频和阻尼比。

| Abstract: | The influence of isolation frequency and damping ratio on the seismic response of an isolation storage tank with a volume of 20000m3 under both anchored and unanchored conditions is investigated using the finite element analysis(FEA) program ANSYS.Additionally,the isolation effect is estimated under the maximal stress in order to identify the optimal isolation frequency and damping ratio. |

| Keywords: | storage tank seismic response isolation stress |
