N2 - The damping characteristics of structures is the most difficult modeling information to obtain in structural design against dynamic loads. Typically in engineering practice, a proportional damping coefficient matrix is assumed, which may result in large errors. In this paper, a unified view of existing damping modeling is given. A comprehensive modeling approach for damping of structures is presented. The new modeling method is based on the simultaneous consideration of energy dissipation and energy transfer in vibration systems. This new approach of damping modeling also provides a better understanding of the dynamic responses of structures with added energy dissipation components and/or devices.
