Uncertainty assessment of structural modeling in the seismic response analysis of nuclear facilities

Choi, B.  ; Nishida, Akemi  ; Muramatsu, Ken*; Takada, Tsuyoshi*  

In order to clarify the influence of the modeling method on the result of seismic response analysis of nuclear facility, seismic response analysis using various simulated input ground motions was carried out and the uncertainty of response results were statistically analyzed. In particular, we focused on the difference of the response due to the structural modeling method (a conventional sway-rocking model and 3D FE model), and the relations among the input level, floor position, and response results were described and discussed.
