Development and Application of Realistic Earthquake Time Histories Compatible with Multiple-Damping Design Spectra

This paper describes the development and application of a new method for generation of realistic synthetic earthquake time histories compatible with multiple-damping design spectra. The effectiveness of this new method is demonstrated by applying it to adjust actual earthquake time histories to match the design spectra while minimizing perturbations on their characteristics. The paper also demonstrates that seismic responses of structures based on such spectrum-compatible realistic time histories are consistent with those obtained from analyses using an ensemble of time histories.
