Discussion on Papers 11 and 12

MR B.M. NEW (Transport and Road Research Laboratory, Crowthorne): I was most impressed by the correlations shown by Dr Medearis (Figs 1-5) between the actual structural motions measured and their analytical models. Were these analytical models produced as true predictions before the explosions or was there some feedback of data subsequent to the event?

DR MEDEARIS (Paper 11): The analytical models of the structure were developed prior to the event. Initial structure response predictions were necessarily based on predicted ground motions. The correlations shown were obtained using the actual recorded ground motions. They depict comparisons of the recorded and theoretical structural responses.
