Dynamic response index

WebDynamic responses of the structures with and without MR dampers can be got through elastic time-history analysis. Fig. 8.4 shows the displacement and acceleration time-history responses of the top node (node 40). It can be seen that the peak values of the displacement responses are reduced by 23.4% and 44.1%, respectively, for the passive … WebRepeated roots (of multicapacity processes) lead to a sluggish response. Tanks-in-series is a good example in this respect. With higher-order models, we can construct approximate reduced-order models based on the identification of dominant poles. This approach is used in empirical controller tuning relations in Chap. 6.
