A detailed dynamic analysis, presented in a series of reports, was conducted on the seismic response and structural safety of key subsystems (steam generator, high pressure steam piping, coal handling equipment, cooling tower, chimney) of Unit no. 3 of TVA at Paradise, Kentucky in order to: (1) determine for the key components the natural frequencies below 50 Hz and the corresponding normal modes; (2) determine response of plant to seismic disturbances; (3) verify through full scale tests results obtained in (1) and determine estimates of damping needed in (2); (4) determine potential failure modes of major structural components; and (5) determine a spare parts policy for a power system so that outages due to damage from seismic disturbances are minimal. Analytical and experimental methods are used. Two elevated coal conveyors are modeled, using simple beams with appropriate static properties. The dynamic characteristics of the models, their natural frequencies, and mode shapes were found by using the finite element approach, and responses determined by modal analysis. Results are shown in linear and tabular form, based on application of stresses equal to those of the 1940 El Centro earthquake.
