Research on the FSI dynamic model of large span beam aqueduct
Based on the structural dynamic analysis theory and fluid structure interaction theory, this paper puts forward the improved pseudo 3D FSI computing mode by the existing pseudo 3D model of large span beam aqueduct. In this paper, the model can not only achieves two-way synchronization FSI of the aqueduct with large sloshing water, but also greatly improves calculating efficiency. So the model can be used for calculating and analyzing the joint multi-span aqueduct considering FSI. In addition, the improved pseudo 3D FSI model can be used to calculate the aqueduct with stiffening structure. One segment of dongshen water supply aqueduct is analyzed by employing improved pseudo 3D FSI model，which yield much close results compared those using 3D finite element model. Therefore the improved pseudo 3D dynamic analysis method is proved to be a practical dynamic analysis method for dynamic analysis and seismic design of large span aqueduct structures with high efficiency.
