โœฆ Synopsis

This paper examines the vibration behaviour of non-classically damped systems in the frequency domain. Errors in the frequency response incurred by neglecting off-diagonal entries of a diagonally dominant modal damping matrix are assessed. The exact response is shown to be equivalent to an infinite Taylor's series, and it is demonstrated that the commonly employed approximation of ignoring off-diagonal entries of the modal damping matrix is equivalent to retaining one term of the series. The frequency dependence of coupling of the non-classical modes is obtained.

Mode-superposition analysis is an efficient tool for the evaluation of the response of linear systems subjected to dynamic agencies. Two well-known mode-superposition methods are available in the literature, the mode-displacement method and the mode-acceleration method. Within this frame a method is
