The Nonlinear Seismic Response Analysis of Ap1000 Nuclear Island Shield Building Considering Fsi


Abstract eng:
The cardinal component of the AP1000 nuclear island passive containment cooling system which is the much more different from other normal ones is the huge gravity water tank. This paper focus on the seismic response of AP1000 nuclear island shield building by creating a 3-D finite element model while takes the FSI into account. Then five different water levels have been studied, the water ratio of the water tank are 0%, 30%, 60%, 80% and 100% respectively. The natural vibration characteristics of the structure can be researched by the analysis of the refined-finite element model. The seismic motion record which is commonly used for the seismic analysis of the nuclear island is inputted as the earthquake loading. The displacement response, first principal stress response and response spectra of the important floors for the five water levels are analyzed to analyze the influence of the FSI to the seismic response of the shield building. The PGA of the input ground motion record is 0.3g, 0.6g and 0.9g to research the nonlinear seismic response of the AP1000 nuclear island shield building.
