The development of a floor response spectrum (FRS) is very important for a seismic risk assessment of nuclear power plants. In the case of non-isolated nuclear power plants, the methodology regarding FRS generation has already been developed. But in the case of seismic isolated NPP structure, the methodology for developing floor response spectrum is not been determined yet. Therefore, in this study, shaking table tests for a seismic isolated frame structure were performed for the development of the floor response spectrum. For the shaking table test, a two-story artificial frame structure was manufactured. For the isolation devices, a lead rubber bearing and an EradiQuake system (EQS) were used. An artificial input seismic motion, which was generated for the NRC Reg. guide 1.60 design spectrum, was used but low-frequency range should be cut off for a decrease of the shaking table displacement. One-, two-, and three-dimensional seismic input motions were considered for the assessment of the horizontal bidirectional and vertical directional effects. Through this test, whether a horizontal bi-directional seismic input can make a difference in the floor response, and moreover, whether the vertical input motion can make a change in the horizontal floor response, were investigated.
