| 摘 要： | 本文考虑液固耦联及底板几何非线性与土壤弹性，建立了液－固－土耦合的储液罐翘离分析力学模型。算例表明，恢复力矩与翘离角之间的关系可以表达为分段线性，翘离将使地震响应增大。

| Abstract: | The mechanic model for analyzing uplift vibration of tanks is presented in consideration of fluid-solid coupling and geometric nonlinear of the bottom plate and elasticity of soil.The results show that the relationship between restoring moment and uplift angle can be described by piecewise linear,and the uplift results in the increasement of seismic moment. |
