Abstract : Results are presented from ground motion calculations of Events II and III of the MIDDLE GUST test series. The calculations were performed using large and small strain versions of the LAYER code in which the material behavior of the ground was described and fit by means of a cap model and the surface loading was fit to a calculation of Needham. The results of the computations are compared to gauge records obtained in the field events. The calculated crater dimensions and peak airblast-induced motions, particularly in the vertical direction, and in reasonable agreement with the field data, while other features of the motion, particularly waveforms, are not as well represented in the calculations. The reasons for the discrepancies are discussed and some points of interest for future study are indicated. (Author)
