本報の目的は、振動数に依存しない複素減衰を用いた計算負荷の小さい鉄筋コンクリートを対象とした等価線形解析手法の原子力発電所の原子炉建屋の耐震設計への適用性を検討することである。これを実現するため、柏崎刈羽原子力発電所7号機原子炉建屋を対象としたある理想的な地盤条件下での非線形及び等価線形地震時挙動に着目した地盤-建物連成系の三次元有限要素法解析を実施した。その結果、等価線形解析手法は、非線形解析手法に対し全体的に概ね良好な対応関係が得られ、その手法の有効性を確認した。

The objective of this study is to evaluate the applicability of the equivalent linear analysis method for reinforced concrete, which uses frequency-independent complex damping with a small computational load, to the seismic design of reactor building of the nuclear power plant. To achieve this, the three-dimensional finite element analyses of the soil-structure interaction system focusing on the nonlinear and equivalent linear seismic behavior under an ideal soil condition were performed for Kashiwazaki-Kariwa nuclear power plant Unit 7 reactor building. From these results, the equivalent linear analysis method showed a generally good correspondence with the nonlinear analysis method, and the effectiveness of the method was confirmed.
