State-of-the-Art for Assessing Earthquake Hazards in the United States. Report 24. WES RASCAL Code for Synthesizing Earthquake Ground Motions.
Abstract
A computer code (RASCAL) has been developed to provide realistic predictions of ground motion parameters for applications to earthquake engineering risk assessment. The code incorporates random vibration theory (RVT) to calculate peak value of acceleration and velocity in addition to response spectra for specified earthquake source and propagation path parameters. To generate synthetic time histories, the code combines the phase spectra from observed strong motion records to a theoretical Brune modulus. The above techniques are also employed to produce an acceleration time history whose response spectrum matches a specified target or design response spectrum.
