Abstract

Optimal design of two simple oscillators coupled by visco-elastic connection under seismic excitation is discussed. A solution to determine the optimal values of the coupling stiffness and damping coefficient is presented. The connection is described by both Maxwell and Kelvin-Voigt damper model. The response of the system under white noise seismic excitation is used to evaluate selected performance indexes varying the two control parameters. The procedure is enriched by considering the effects of ground acceleration represented by a Kanai-Tajimi filtered non-stationary process.
