Abstract : This study evaluates the effectiveness of using sinusoidal input motions in seismic ground motion studies. The computer program SHAKE-88 is used to compute the peak surface accelerations in three different soil profiles subjected to sinusoidal and earthquake input motions. The input motions are scaled to cover a range of maximum accelerations and frequencies. A comparative analysis is made of the sinusoidal and earthquake normalized peak surface accelerations (amplification factors) resulting in the three soil profiles. Results from 690 SHAKE-88 computer runs indicate that the peak surface accelerations induced by the sinusoidal motions generally come very close to matching those induced by the earthquake motions.
