Under earthquake action, the reinforced concrete structure at the edge of the CAP1400 nuclear power plant foundation slab will\nbe uplifted. In order to determine the seismic performance of this structure, a 1 : 12 scale shaking table test model was fabricated\nusing gypsum as simulated concrete in order to meet scaled design requirements. By testing this model, the seismic response of\nthe structure with consideration of the foundation uplift was obtained. Numerical analyses of the test model and the prototype\nstructure were conducted to gain a better understanding of the structural seismic performance. When subjected to earthquakes,\nthe foundation slab of the nuclear power plant experiences a slight degree of uplift but remains in the elastic stage due to the weight\nof the structure above, which provides an antioverturning moment. The numerical simulation is in general agreement with the test\nresults, suggesting numerical simulations could be accurately employed in place of physical tests. The superstructure displacement\nresponse was found not to affect the safety of adjacent structures, and the seismic performance of the structure was shown to meet\nthe relevant design requirements, demonstrating that this approach tomodelling can serve as a design basis for theCAP1400 nuclear\npower demonstration project.
