Abstract
This paper utilizes complex modal analysis technique to deal with a non-classical damping composite system, which consist of a primary and a secondary systems. The outcome is presented by a response spectrum which is more convenient in the application of design. The interaction, tuning and non-classical damping between sub-systems must be taken into account in the structural analysis of composite system. The present study obtains the modal characteristics of the composite system by simple analysis method. The method offers a less numerical labor than the ordinary one. In regard to a composite system with added viscoelastic dampers, the study focuses on each individual sub-system and modifies the modal shapes by two phases. By using so, the analytical complexity is reduced substantially.
