Abstract This study introduces a new procedure for three-component spectral matching of seismic ground acceleration records. The involves preserving the phase angle and varying Fourier amplitudes to match spectra recorded records with provided target spectrum that represents values motions in three orthogonal directions. Several were matched against two response test method. An accurate converg...
