Abstract
The response of two adjacent single degree-of-freedom (SDOF) structures connected by nonlinear viscous damper under base excitation, modeled as stationary white-noise random process is investigated. Considering nonlinear force-deformation phenomenon of nonlinear viscous damper, the dynamic response of connected structures is obtained using the equivalent linearization technique. A parametric study is carried out to examine the influence of system parameters such as mass ratio and frequency ratio on optimum damping of damper and corresponding response. It is found that frequency ratio affects the performance of damper and corresponding response significantly, whereas, the effect of mass ratio is marginal.
