000009390 520__ $$2eng$$aCharacterization of energy damping sources in structures has been an active area of research for many years. Despite all the improvements in modeling and analysis techniques for capturing the behavior of structural components of building, our understanding about inherent energy dissipating characteristics is far from reality. The current state-of-knowledge for modeling inherent structural damping is to use a linear viscous damping model that assumes the global energy dissipating characteristics of a structural system is proportional to its dynamic degrees of freedom velocities, and does not depend on the level of nonlinear behavior of the structural system. On the other hand a proportional damping model called Rayleigh damping is used to model the energy dissipation characteristics of the structure for decades. This paper studies the consequences of using Rayleigh damping in analysis of inelastic structures. It is shown that using the stiffness proportional part of the damping based on the original damping ambiguous forces will develop which may result to overestimated designs and lack of static equilibrium will be observable. A proposed model is used to control this source of problem in this paper.
