Simulated earthquake motions compatible with multiple-damping response spectra for the design of nuclear power plants

Since, the various structures, components and equipment of nuclear power plants have different damping values, in order to obtain realistic results in the response analysis of them, the use of input earthquake motions compatible with multiple-damping design response spectra is required. In this study, the problem of generation of an accelerogram compatible with a set of response spectra with different damping values is examined. This approach also covers the case of synthetic accelerograms compatible with a single damping response spectrum
