D. Key, THE INFLUENCE OF DAMPING AND PARAMETER UNCERTAINTY ON SEISMIC SECONDARY RESPONSE SPECTRA - A RANDOM VIBRATION APPROACH, Nuclear Engineering and Design, 166(1), 1996, pp. 1-7
A random vibration formulation is used to examine the frequency depend
ence of the relationship between damping and response in single-degree
-of-freedom systems. This is then extended to secondary systems and th
e possibility of non-conservative approaches to design including the e
ffect of parameter uncertainty.
