摘要
本文采用交替解法对地震条件下储液容器的动态响应问题进行了实例分析和计算。首先推导出流固耦合系统在地震条件下的有限元模型。然后,对在水平地震激励条件下的圆柱形储液容器,采用交替解法进行了计算,并将其与整体解法进行了比较。结果表明交替解法具有更好的计算效率。
This paper applies a staged method to the dynamic response analysis of liquid-filled tank under earthquake. A finite element model of liquid-filled tank is set up. Taking into account earthquake effect leads to additional load to the coupling equations. A cylindrical liquid-filled tank is studied using the model. It is found that the response of structures to the earthquake loading is much different from that of fluid. The advantage of the staged method is also verified. It is shown that the staged method is more efficient and cost-effective than the whole solution method.
