摘要：

The uncertainty associated with damping in structural systems is identified and discussed. A second-order perturbation technique is utilized to examine the effects of damping variability on the transient and steady-state dynamic response of structural systems. The results demonstrate that the uncertainty in damping indeed influences the system response. The effects are more pronounced for higher variability of damping values. © 1990.
