Seismic Category I Structures Program: Final report, FY 1983-84
This report summarizes the results obtained from a series of simulated seismic tests on scale models of a prototypical Category I nuclear power plant auxiliary building, representing a reinforced concrete, diesel generator building. Two sizes of model structures were used: 1/10 scale and 1/30 scale. Model construction, test methods, instrumentation, data reduction techniques, experimental results, comparison of experimental and computed results, and conclusions are presented in this report. Values of structural stiffness obtained from both static and dynamic tests are found to be significantly lower than values of stiffness computed using the usual design methods. Values of modal frequency obtained from dynamic tests are compared to computed values. Decreasing modal frequencies with increasing seismic input are reported. The effective damping of these test structures is determined from the test results. The results obtained from the two different size (1/10- and 1/30-scale) models are compared. 10 refs., 31 figs., 8 tabs.
