Response Spectrum 1
Response Spectrum 1 : A curve showing the computed maximum response of a set of simple single-degree-of-freedom harmonic oscillators with chosen levels of viscous damping and different natural frequencies to a particular record of ground acceleration. Response spectra, commonly plotted on tripartite logarithmic graph paper, show the oscillator's maximum acceleration, velocity, and displacement as a function of oscillator frequency for various levels of oscillator's damping. A computational approximation to the response spectrum is referred to as the pseudo-relative velocity response spectrum (PSRV). These curves are used by engineers to estimate the maximum response of simple structures to complex ground motions. See Anderson (2003)
