Application of Fluid-Structure Interaction Analysis in the Design of Upper Water Tank Structure of HPR1000 Outer Containment

Based on the basic principle of fluid-structure interaction, this paper make a finite element analysis of seismic on upper water tank of HPR1000 outer containment by CEL method in ABAQUS software. Firstly, structure is simulated the by Lagrange grid and the water in upper water tank by Eulerian grid; secondly, coupling contact between water and structure is defined; finally, the calculation results are got by running an explicit dynamic solver to makes a time history analysis of fluid-structure interaction finite element model under the seismic, and the results will be used in the structure design of outer containment and upper water tank.
