Abstract |
A procedure to select ground motions with less change in wave form characteristics, which result from spectral matching of recorded accelerograms, is developed for input ground motion sets that match a target response spectrum for probabilistic seismic performance evaluation of nuclear power plant structures. For this purpose, indices that comprehensively evaluate various wave characteristics is proposed. Using the proposed procedure and indices, ground motion sets with different wave characteristic changes are determined. Probabilistic seismic performance evaluation of a nuclear power plant containment building is conducted using those ground motion sets. Influence of change in wave form characteristics by spectral matching is investigated for probabilistic seismic characteristics.
