Application of Reduction Methods to Nuclear Power Plant Structures.

摘要

Guyan Reduction is used extensively to reduce the degrees of freedom of a structural model prior to performing dynamic analysis. Prior studies have shown that large errors in member loads may result when Guyan Reduction is used. This conclusion was based upon a study of structures which are smaller and of somewhat different types than are usually encountered in the structural analysis of nuclear power plant facilities. The objective of the study is to extend the prior results to structures more typical of nuclear power plants. Two structures are considered and large errors in member loads are again found when reduction methods are used.
