| 摘 要： | 储油罐在水平地震作用下会出现罐底提离而导致储油罐发生提离破坏,影响储油罐的可靠性。为了研究立式储油罐在地震作用下的抗提离可靠度情况,文中总结建立了在储油罐抗提离可靠度分析中涉及的随机变量的概率模型,运用可靠性分析的JC法对不同工况下的储油罐进行了抗提离可靠度计算,得出了储油罐在地震作用下的提离破坏规律。通过计算实例可以看出,对大型储油罐在地震作用下的抗提离可靠度分析是切实可行的。

| Abstract: | The lift-off will occur in bottom of vertical storage tanks under strong earthquakes,which can destroy the whole storage tank,and the reliability of the storage tank is influenced.In order to studying the anti-life-off effect of the storage tank under earthquakes,a probabilistic model of the random variable is established,which is concerned to the reliability analysis on anti-lift-off of the storage tank.The reliability calculation on the anti-lift-off effect of the storage tank is implemented by using the ... |
