Abstract
This paper describes briefly the fabrication, preparation, and erection details for a 1/10th scale plastic (polystyrene) model of a steel foundation supporting a nuclear turbine-generator-exciter unit. The foundation consists of box-section beams and columns with a large number of diaphrams. Natural frequencies of the foundation model with column bases fixed to the blocks were obtained with and without mass representation for the turbine-generator-exciter unit on the model deck. Selected (fundamental) mode shapes of the model were obtained experimentally for the two test cases. Details of the test procedure and instrumentation used are also given in this paper. Corresponding analytical data for the model obtained by using NASTRAN, the finite element computer program, are examined briefly in the paper. Comparison between the experimental and analytical data (frequencies, mode shapes) given in the paper showed excellent agreement.
