摘要
为了找出一种更加简便的渡槽结构抗震计算的时程分析方法 ,应用解析方法分析渡槽中流体对结构的作用 ,应用有限元法分析结构的振动 ,基于流体 -结构的耦合 ,建立起耦联系统总的运动方程 ,由 Newmark直接积分法可得到系统的地震反应历程。
The effect of fluid in aqueduct on structure is studied using analytical method, and the structure vibration is analyzed using finite element method in this paper. Based on the interaction of fluid and structure, the general movement equation of the coupled system of fluid movement is derived. Through Newmark direct integral, the seismic response process of the system can be obtained.
