A UNIFORM ESTIMATION OF SOME BASIC GROUND MOTION PARAMETERS

A dataset of 690 strong motion component records of horizontal accelerations are analysed to derive predictive relationships for Arias Intensity, duration and number of pulses as functions of acceleration level as well as their dependence on the magnitude and distance of the source. The relationships show that the records should follow the patterns set by such relationships and cannot entirely be random. The use of some of the parameters to generate artificial time histories of acceleration is shown merely as an example.
