Two analog methods of simulating earthquake motions are presented; one method uses sections of Gaussian random function with given power spectrum; second method uses hybrid computer that permits any given type of ground motion to be simulated; linear single-degree-of-freedom systems were excited by simulated earthquakes and their responses were measured; base shear was used as measure of response and empirical formulas were developed for base shear as function of mass and period of system and magnitude of ground acceleration.
