A. Saudy et al., A NEW STOCHASTIC-ANALYSIS FOR MULTIPLE SUPPORTED MDOF SECONDARY SYSTEM .2. TUNING AND SPATIAL COUPLING EFFECTS, Nuclear Engineering and Design, 147(3), 1994, pp. 251-262
A new stochastic analysis is developed to estimate the response of mul
tiply-supported multi-degree-of-freedom (MDOF) secondary systems to dy
namic loading. The preceding paper illustrates how the effect of the d
ynamic interaction between the secondary and primary systems is includ
ed in the proposed stochastic analysis. The effects of both tuning and
spatial coupling are covered in this paper. First, the terms associat
ed with the cross correlations are defined. Then, a section is assigne
d to demonstrate how the tuning character can be accounted for. Subseq
uently, numerical examples are provided in order to demonstrate the si
gnificance of both effects of tuning and spatial coupling in the stoch
astic analysis of secondary systems.
