Abstract
James Lord - “Real-time simulated earthquake motion of high rise structures"
Highlights
Mr McKenzie : From the designer' s point of view, the dynamic analysis system described in this article is one of the best and most comprehensive that has yet been reported for response in the elastic range
The author's procedure enables the designer to make this assessment, because it gives the direct integration response corresponding to the combination of all modes, but it gives the separate magnitudes and time histories of the individualmode components the method has, on the one hand, the advantage of the direct integration method in giving the exact combined response to one earthquake, and on the other hand allows the designer to see if the individual modes have any peculiarities in their magnitudes or time history or phase relationships that should be allowed for in interpreting the results
The comprehensive data given by the system described enables adjustments of this type to be madev by the designer. ' Again, it allows the causes of local low values in the storey responses to be investigated, so that the designer can decide whether they correspond to the peculiarities of one particular earthquake record and should be scaled up to give a more general result
Summary
Mr McKenzie : From the designer' s point of view, the dynamic analysis system described in this article is one of the best and most comprehensive that has yet been reported for response in the elastic range. The second mode components should really be scaled up to the ordinates of smoothed response curves, when the designer comes to interpret the results.
