A Shaking Table Test On The Containment Of Nuclear Power Plant And Numerical Analysis

With the increase of world energy demand and the limit in carbon emission, thedevelopment of nuclear power has become the focus of the world. Compared with15%of theworld average, the account for the generation of electrical energy in China is less than2%.Therefore, the development of nuclear power will have a good prospect in China.Seismic safety of nuclear power plant has a high level, but seismic technology of nuclearpower still cannot meet the social needs. The earthquake is random and the structural isuncertain. The damage of earthquake to the containment will cause serious social impact andeconomic losses with nuclear leakage of radioactive material. In this paper, the research forcontainment was accomplished by shaking table test and numerical simulation. After studyingmechanism and failure process of containment, it can provide basic information for improvingthe seismic performance of containment.Based on the similarity theory, the preparatory process for containment test wascompleted besides test weight and seismic wave compression. By different shocks, the modelof containment was carried out to test by the shaking table in the Institute of EngineeringMechanics of China Earthquake Administration. The results, such as dynamic response aboutthe key position of the displacement, acceleration and stress were tested. Subsequently, basedon the dynamic response during the test data, time-history and spectral analysis were made byusing the MATLAB language. The test results of the seismic performance were provided byanalysis.By accounting for the dimensions of the model of containment and the mechanicsparameters of concrete and steel, the finite element model is established and vibration test issimulated by using SAP2000. From the point of numerical simulation, the factors such asactual counterweight and permanent connection are considered systematically. The numericalsimulation was proven to be right according to the comparison of numerical simulation andexperiment results.This article looks at the methods of research such as seismic resistant performance,applied theory analysis, experiment research and numerical simulation, also it applies somuch knowledge about structural engineering, seismic engineering and numerical simulation, from the point of spectrum and time history analysis; the research result is aimed to improvethe seismic resistant performance of containment.
