MISERS BLUFF Phase I ground shock analysis of the multiple burst experiments. Interim report 1 Jan-1 Jun 78

The multiple burst experiments of Misers Bluff Phase I provided the data base for the evaluation of the superposition principle for ground motions. In addition, this data will be used in the development of a general prediction procedure for the multiple burst environment. Superposition of single burst waveforms is compared to the multiple burst waveforms on a component by component basis. Quantitative evaluation of these comparisons is made and presented for the three multiple burst experiments discussed in this report. In addition, state-of-the-art empirical predictions are compared in a like manner. Phenomenology associated with these experiments is discussed and related to the waveforms observed in the various experiments. The understanding of this phenomenology will aid in the development of the prediction procedure for the multiple burst environment. In addition, recommendations aimed at furthering the understanding of the multiple burst phenomenology are presented.
