[en] One of the earthquake motion simulations computer generated is termed the wave superposition method. Its elemental wave amplitudes are determined by target convergent calculation on some smoothed response spectra. Phases are usually given with uniform random numbers. We seldom experienced on response spectrum over the level of the target response spectrum with lower damping. We therefore established a generation method to fit the response spectra simultaneously with 2 kinds of damping. (orig.)
