요약2 The finite element analysis (FEA) of the nuclear power plant (NPP) system is generally excited by a single representative acceleration data as the supporting points have similar elevations. However, NPP pipes have multiple supporting points so that the multi-support excitation methodology which applies excitation on each support is generally considered to obtain the exact seismic responses. In this research, we study input methods for conducting multi-support excitations in FEA, and all the methods are constructed under time history analysis considered more precise than floor response spectrum analysis. Three types of input methods, namely large mass method, mode superposition transient, and displacement input transient analysis, were considered in this research. As a result, we conclude that all the methods generate similar motion parameters to the reference acceleration data on each supporting point. In addition, it is considered whether there is an appropriate input method to simulate another type of supports by changing the boundary condition on the support area.
