- Abstract
This investigation is concerned with the seismic response of one-story, one-way asymmetric linear and non-linear systems with non-linear fluid viscous dampers. The seismic responses are computed for a suite of 20 ground motions developed for the SAC studies and the median values examined. Reviewed first is the behaviour of single-degree-of-freedom systems to harmonic and earthquake loading. The presented results for harmonic loading are used to explain a few peculiar trends-such as reduction in deformation and increase in damper force of short-period systems with increasing damper non-linearity-for earthquake loading. Subsequently, the seismic responses of linear and non-linear asymmetric-plan systems with non-linear dampers are compared with those having equivalent linear dampers. The presented results are used to investigate the effects of damper non-linearity and its influence on the effects of plan asymmetry. Finally, the design implications of the presented results are discussed. Copyright © 2005 John Wiley & Sons, Ltd.
