Monte Carlo analyses are usually performed in order to characterize the uncertainty in system structural dynamic responses. In this context, Component Mode Synthesis may be used to speed up the Monte Carlo computation time. When non-proportional damping is present in the system being modelled, it is necessary to introduce complex modes in the formulation to correctly account for the damping. This work presents a method for uncertainty propagation in complex modes based Component Mode Synthesis models for systems with uncertain damping.
