Design Spectrum
Design Spectrum : The specification of the required strength or capacity of the structure plotted as a function of the natural period or frequency of the structure and of the damping appropriate to earthquake response at the required level. Design spectra are often composed of straight line segments and/or simple curves, for example, as in most building codes, but they can also be constructed from statistics of response spectra of a suite of ground motions appropriate to the design earthquake(s). To be implemented, the requirements of a design spectrum are associated with allowable levels of stresses, ductilities, displacements or other measures of response. See: Response Spectra; also Housner (1970)
