| 摘 要： | 本文根据作者提出的考虑了罐底板柔性及地基弹性作用的动力提离分析模型,对地震作用下储液罐的动力提离效应进行了探讨。对比电算结果表明,不能作出考虑了提离比不考虑提离动力响应就会肯定增大或肯定减小的简单结论;动力提离效应则与罐本身的动力特性、地震波的频谱特性以及地基的弹性大小等有关。

| Abstract: | On the basis of dynamic uplift analysis model presented by authors,this paper investigates the dynamic effect of the liquid storage tank under the earthquake action . In this model the flexibility of bottom plate of the tank and the elasticity of the foundation are considered. The contrast calculation results indicate that it can not simply draw a conclusion that the dynamic response after consideration of uplift is surely larger or smaller. This is related with the vibration behaviour of the tank .the excitation frequency of earthquake wave and the elasticity of the foundation |
